Dog Harness Reviews in Australia for Puppies: Growth & Adjustment Issues

Key Takeaways

• Puppies outgrow harnesses quickly, so the “best” puppy harness in Australia is usually the one with the widest adjustment range and a shape that avoids rubbing as the chest deepens.
• Aim for a snug fit with two flat fingers between straps and skin, and re-check fit every 2–4 weeks during growth spurts. RSPCA-related guidance commonly references the two-finger fit check for harness comfort and security. (Source: RSPCA Pet Insurance)
• For most puppies learning lead manners, a front-clip option (ideally on an anatomical “Y-front”) can reduce pulling leverage compared with a back-clip only set-up.
• Avoid harness designs that sit across the point of the shoulders or crowd the armpits; these commonly cause gait restriction and chafing, particularly as puppies gain muscle.
• In Australian heat, prioritise breathable mesh and minimal coverage, and plan walks for cooler parts of the day. (Source: PetCareShed)
• Puppies have soft growth plates and are more vulnerable to overuse injuries. Keep “structured” lead walks short and gradual. RSPCA guidance supports short, slow walks and building up. 
• Many Australian jurisdictions require dogs to be microchipped by a certain age and/or before sale/transfer, but rules differ by state. Check local council requirements.

PetCareShed’s Handpicked Dog Comforts

Introduction

Reading dog harness reviews for puppies can feel frustrating, because most reviews focus on adult dogs: how a harness performs on long hikes, how it holds up to strong pulling, or whether it looks good. Puppy owners in Australia are dealing with different realities—rapid growth, changing proportions, toilet-training routines that require frequent short outings, and a nervous system that is learning what “being on lead” even means.

A puppy harness is not just a smaller version of an adult harness. It must cope with:

• A chest and ribcage that can change size noticeably in a few weeks
• A neck that is still developing, and in many breeds is relatively delicate
• A coat that may shift from puppy fluff to adult coat, affecting friction and heat retention
• Behavioural development: biting, freezing, “crocodile rolling”, sudden startle responses, and inconsistent walking patterns

This article reviews puppy harness choices in an Australia-specific way, with a strong focus on growth and adjustment issues. Rather than ranking brands, it explains how to assess harness types, fit, materials, and safety features so you can interpret reviews accurately and select a harness that is likely to work for your puppy’s stage of development.

How to Read Puppy Harness Reviews (and Spot What’s Missing)

Many harness reviews are written after a single fitting session or a few walks. For a puppy, that is rarely enough time to understand the real challenges. A harness that seems “perfect” at 10 weeks may be rubbing by 14 weeks, and slipping by 16 weeks after a growth spurt.

When reading reviews, look for evidence that the reviewer considered growth and development:

• Time frame tested: Was it tested over at least 4–8 weeks? Did the puppy grow significantly during the review period?
• Re-checking fit: Did the reviewer mention re-adjusting straps regularly, not just once?
• Body shape: Is the puppy a deep-chested breed, a broad-chested breed, a sighthound-type shape, or a compact brachycephalic type?
• Climate conditions: Australian heat can change what “comfortable” means. A padded harness that is fine in a cool climate may cause overheating in Queensland or northern WA.
• Leash training context: A front-clip can appear “magical” in reviews, but the best results usually occur when it is paired with training.

Review language that can be misleading

Certain phrases appear repeatedly in puppy harness reviews, and they are not always helpful:

• “Escape-proof”: No harness is genuinely escape-proof if a puppy is highly motivated and the fit is poor or the body shape is challenging. A better claim is “reduced risk of backing out,” usually through additional security points.
• “No pull”: Harnesses can reduce leverage or redirect the body, but consistent pulling behaviour is best addressed through training and management.
• “One-size-fits-all”: Puppies vary dramatically in proportions, even within the same age range.

A useful review often includes specific fit checks, such as the two-finger rule and strap placement behind the armpits. Australian veterinary guidance commonly describes a harness as needing to be snug but not tight with room for two flat fingers.

Puppy Growth: Why Harness Fit Changes So Quickly

The most important context for puppy harness reviews is growth. Puppies generally gain weight, deepen through the chest, and broaden through the shoulders as muscles develop. Even if the puppy is not “bigger” overall, the shape can change.

Growth plates and why controlled walking matters

Puppies have growth plates (physes) that remain open while bones lengthen. Guidance on exact closure times varies by breed and individual, but it is widely accepted in veterinary resources that closure can take longer in larger breeds and may extend up to around 18 months or more in some cases.

The practical relevance to harness choice is that a harness should not encourage intense, repetitive pulling or restrict natural shoulder movement, particularly during long structured walks. Short, controlled walks are generally recommended for young puppies.

RSPCA guidance supports short, slow walks and building up gradually while puppies are growing. (Source: RSPCA Knowledgebase) https://kb.rspca.org.au/categories/companion-animals/dogs/puppies/how-should-i-exercise-my-puppy

Typical “shape changes” that affect harnesses

Common puppy developments that change harness fit:

• Chest drop and rib expansion: The girth measurement can increase quickly.
• Neck thickening: Particularly in breeds that develop strong neck musculature.
• Shoulder and upper arm muscle: Can increase friction near the armpits.
• Coat changes: Less fluff can mean less cushion against webbing.

A practical fit-check schedule for puppies

Harness reviews rarely give a fit-check schedule, but it helps to follow one:

• 8–16 weeks: check fit weekly if your puppy is growing rapidly
• 4–8 months: check every 2–3 weeks
• 8–12 months: check monthly (or sooner if weight changes)

If your puppy is between sizes, many fitting guides suggest selecting the size that provides more adjustment room rather than a tight “perfect fit today” option. (Source: Petbarn) https://www.petbarn.com.au/petspot/dog/find-right-harness-dog/

Harness Types in Australia: What Reviews Often Get Right (and Wrong)

Harness type strongly affects how a puppy moves, how the lead pressure is distributed, and how easily the harness can be adjusted during growth.

Y-front (anatomical) harness

A Y-front harness typically forms a “Y” shape on the chest, running from the sternum up between the front legs and splitting toward each shoulder.

Why it often suits puppies

• Usually offers good shoulder clearance when correctly designed
• Can be highly adjustable across neck and girth
• Often more stable than narrow strap designs

Common issues seen in reviews

• The chest piece can sit too high and contact the throat if adjusted incorrectly.
• If the girth strap sits too close to the armpits, rubbing can occur during growth.

H-style harness

An H-style harness uses two loops (neck and girth) connected by straps along the back and chest.

Strengths

• Simple, lightweight, often breathable
• Adjustable and easy to put on and remove

Potential drawbacks for puppies

• Some designs can drift toward the armpits if not fitted carefully
• Can rotate on narrow-bodied puppies

Vest-style harness

Vest harnesses use more fabric coverage across the chest and sometimes the back.

When they can work

• Very small puppies with delicate skin
• Puppies that are uncomfortable with thin straps

Australia-specific caution

• In warm climates, vest coverage can trap heat and moisture, increasing the risk of skin irritation.

Step-in harness

Step-in harnesses are popular for puppies that dislike overhead handling.

Practical considerations

• Fit around the chest and legs must be precise to prevent rubbing
• Many step-in designs offer less neck adjustment, which can be limiting during growth

Front-clip vs back-clip attachment points

A key “review feature” is where the lead attaches:

• Back-clip: often comfortable and simple; can allow more pulling leverage.
• Front-clip: can reduce pulling by turning the body toward the handler.
• Dual-clip: provides flexibility; can be used with a double-ended lead for steering.

Research indicates that dogs may pull with different patterns depending on restraint type, and there is evidence that back-connection harnesses can be associated with higher pulling forces in certain contexts compared with collars. (Source: PMC study) https://pmc.ncbi.nlm.nih.gov/articles/PMC8450523/

This does not mean a harness is “bad.” It means a harness should be chosen and used with awareness: if a puppy learns to pull hard into a back-clip harness, the habit can become entrenched.

What a “Good” Puppy Harness Review Should Assess

A puppy harness review should assess more than “it fits” and “it looks nice.” The following criteria are especially relevant in Australia.

1) Adjustment range and strap geometry

For puppies, adjustment range matters more than premium materials. Look for reviews that mention:

• Multiple adjustment points (neck, girth, chest length)
• Whether straps adjust symmetrically on both sides
• Whether strap ends stay secured after adjustment

2) Anti-rub design near the armpits

Armpit rubbing is one of the most common puppy harness problems. Better reviews mention:

• Whether the girth strap sits far enough behind the front legs
• Whether padding (if present) is soft and does not bunch
• Whether the harness shifts when the puppy trots, not just when it walks

Fitting guidance commonly advises positioning straps to avoid the inner armpit area and using a snug-but-not-tight approach. (Source: PetCareShed) https://petcareshed.com.au/blogs/pet-supplies/how-to-properly-fit-a-dog-harness-avoid-chafing-and-discomfort

3) Heat and moisture management

In many parts of Australia, heat and humidity are the reason a harness that seems “comfortable” becomes uncomfortable.

A strong review will mention:

• Mesh coverage vs heavy padding
• Drying speed after water play or rain
• Whether the harness traps sand at the beach

Heat-management guidance for Australian conditions emphasises breathable materials and avoiding heavy, heat-trapping designs. (Source: PetCareShed) https://petcareshed.com.au/blogs/pet-supplies/best-dog-harnesses-for-australian-summers

4) Durability against puppy behaviour

Puppies chew. Reviews should mention:

• Whether webbing frays when mouthed
• Whether buckles are resistant to cracking
• Whether stitching is reinforced

5) Safety for car travel (when relevant)

Australian road rules and enforcement vary, but safe transport is a serious welfare issue. Reviews that discuss “car harness” use should mention compatibility with:

• Seatbelt tethers
• Crash-tested design (if claimed)
• Fit that does not restrict breathing when seated

A general overview of Australian vehicle transport requirements highlights that restraint is commonly expected to avoid distraction and risk, with specific obligations for open vehicles. (Source: PetCareShed) https://petcareshed.com.au/blogs/pet-supplies/transporting-pets-in-vehicles-legal-safety-requirements-australia

How to Measure a Puppy for a Harness (Correctly)

Incorrect measuring is a major reason puppy harness reviews are negative. Puppies also tend to wiggle, which makes rushed measurement unreliable.

Measurements to take

• Chest girth: around the widest part of the ribcage, typically just behind the front legs.
• Neck base: around the base of the neck where a collar naturally sits (not high near the jaw).
• Chest length (if required): from the sternum area to where the girth strap will sit.

Many Australian fitting guides emphasise chest girth as the critical measurement. (Source: Petbarn) https://www.petbarn.com.au/petspot/dog/find-right-harness-dog/

The “two flat fingers” fit check

A widely cited comfort check is:

• You should be able to slide two flat fingers between strap and skin.

This helps prevent both chafing (too loose can move and rub) and restriction (too tight). (Source: RSPCA Pet Insurance) https://rspcapetinsurance.org.au/pet-talk/how-to-choose-the-right-dog-harness/

Quick at-home measuring tips that reduce errors

• Measure when your puppy is calm (after a meal or short play).
• Use a soft tape measure; if you use string, measure it against a ruler afterwards.
• Record the measurement and date; compare every few weeks.
• If your puppy is between sizes, prioritise adjustment room.

Fit and Adjustment: The Make-or-Break Issue for Puppies

A puppy harness should move with the puppy, not against it. Even a well-designed harness will fail if it is adjusted poorly.

Correct strap placement (practical descriptions)

A useful way to assess fit is to look at the harness in motion.

• From the side: the girth strap should sit behind the front legs, not in the armpit.
• From the front: chest straps should sit centred and not pull across one shoulder.
• From above: the harness should not rotate significantly when the puppy turns.

Signs the harness is too tight

• Shortened stride in one or both front legs
• Panting that seems excessive for the activity
• Fur parting or skin indentation after removal
• Resistance to having it put on

Signs the harness is too loose

• The harness shifts sideways when the puppy sniffs
• The chest piece drifts toward the throat
• The puppy can back out by reversing

A simple “walk-test” routine

After fitting:

1. Walk 10–20 metres on a loose lead.
2. Encourage a trot for a few steps if safe.
3. Turn left and right.
4. Offer a treat and see if the harness rides up when the puppy sits.

If the harness slides or rubs during this short test, it will be worse on longer walks.

Common Puppy Harness Problems in Australia (and How Reviews Should Address Them)

Problem 1: Chafing under the front legs

Chafing often occurs because:

• The girth strap is too close to the armpit
• The harness is slightly loose and moves repeatedly
• The puppy’s coat is changing, reducing natural padding
• Salt, sand, or grass seeds are trapped under straps

Fitting guidance emphasises armpit clearance and correct positioning behind the front legs to reduce rubbing. (Source: PetCareShed) https://petcareshed.com.au/blogs/pet-supplies/how-to-properly-fit-a-dog-harness-avoid-chafing-and-discomfort

Practical adjustments

• Reposition the harness so the girth strap sits further back.
• Tighten in small increments while maintaining the two-finger check.
• Keep the harness clean and dry; rinse after beach walks.
• Consider a lighter harness with less fabric coverage in humid conditions.

Problem 2: Harness overheating in summer

Overheating risk increases when a harness:

• Uses heavy padding or large fabric panels
• Is dark-coloured
• Holds moisture against the coat

Australian summer guidance recommends breathable materials and minimal coverage designs to support airflow. (Source: PetCareShed) https://petcareshed.com.au/blogs/pet-supplies/best-dog-harnesses-for-australian-summers

Practical management

• Choose mesh or open-strap designs.
• Walk in early morning or evening.
• Bring water, and keep sessions short for young puppies.

Problem 3: Harness rotation on narrow or deep-chested puppies

A harness that rotates can cause rubbing and reduce control.

What helps

• A well-shaped chest piece that anchors on the sternum
• Additional adjustment points
• A second security strap (when appropriate)

Problem 4: “Backing out” or escaping

Puppies can reverse quickly when startled. A harness that is too loose or poorly shaped around the neck and chest can allow an escape.

Risk factors

• Neck loop that is too large
• Minimal chest coverage
• Extremely slim build (some adolescent phases)

Management

• Ensure correct sizing and snug adjustment.
• Consider double-point attachment (lead to harness, and a safety connector to collar) while training.

Problem 5: Buckle irritation and fur breakage

Some puppies develop irritation where buckles sit.

What reviews should mention

• Whether buckles are positioned away from pressure points
• Whether strap edges are smooth
• Whether stitching or webbing feels stiff

Australia-Specific Considerations: Climate, Terrain, and Lifestyle

Suburban footpaths, hot surfaces, and short training walks

Many Australian owners walk on concrete footpaths, which can become hot in summer. Even if a harness is breathable, a puppy can still overheat quickly.

Because puppies should have controlled, gradual exercise, it is often more appropriate to:

• Use the harness for short lead sessions
• Use backyard play and enrichment for exercise
• Save longer adventures until the puppy is older and physically conditioned

RSPCA guidance supports short walks and gradual increases. (Source: RSPCA Knowledgebase) https://kb.rspca.org.au/categories/companion-animals/dogs/puppies/how-should-i-exercise-my-puppy

Beach walks and salt/sand exposure

Australian beach culture is a factor that many generic reviews ignore.

Beach-specific harness considerations:

• Quick-drying materials
• Rust-resistant hardware
• Easy cleaning (sand trapped under padding is a common irritation cause)

Bush walks and grass seeds

In some regions, grass seeds can embed in fur and irritate skin under a harness.

Practical steps:

• Choose harnesses with less “pocketing” and fewer folds
• Check under straps after walks
• Groom regularly

A Structured “Review Framework” for Puppy Harnesses

The following framework helps compare puppy harnesses consistently, even when online reviews are vague.

Criterion	Why it matters for puppies	What to look for in reviews	Common red flags
Adjustment range	Growth is rapid	Neck + girth + chest length adjusters	Only one main adjustment point
Armpit clearance	Rubbing risk increases as chest deepens	Mentions strap sits behind front legs	“Leaves red marks” or “hair loss”
Shoulder freedom	Natural gait supports development	Y-front/anatomical shaping; no shoulder cross-strap	“Restricts stride” or “walk looks awkward”
Heat management	Australian summers raise risk of overheating	Breathable mesh, minimal padding, dries quickly	“Too hot” or “stays wet”
Ease of putting on	Puppies fidget and may fear handling	Quick buckles; clear routine; low-stress	Requires wrestling or overhead force
Training compatibility	Lead manners are learned, not bought	Front + back clips; stable D-ring	Only back-clip for heavy pullers

Selecting the Right Harness for Your Puppy’s Stage

A useful approach is to select the harness based on the next 8–12 weeks, not the next 12 months.

Stage 1: Early puppy (8–14 weeks, depending on vaccination status)

Priorities:

• Comfort and positive association
• Simple adjustments
• Low weight
• Easy on/off

Good options often include a lightweight Y-front or simple H-style harness with multiple adjusters.

Stage 2: Juvenile puppy (14 weeks–6 months)

Priorities:

• Stronger hardware (chewing and stronger pulling)
• Front-clip option for training
• More stability to reduce rotation

This is often the stage where owners benefit from a dual-clip harness and a training plan.

Stage 3: Adolescent (6–12+ months)

Priorities:

• Fit stability as body shape matures
• Durability for increased exercise
• Comfort for longer walks

This is also a stage when behavioural pulling can intensify, and a front-clip can remain useful.

Harness vs Collar for Puppies: Welfare and Practicality

One reason puppy owners consider harnesses is concern about neck pressure.

Evidence-based discussions frequently note that collars concentrate force on the neck, and some research indicates physiological changes such as increased intraocular pressure (IOP) in certain contexts with collar use. (Source: PMC article) https://pmc.ncbi.nlm.nih.gov/articles/PMC12036695/

A harness is not automatically better in every respect; a poorly fitted harness can rub, restrict movement, and encourage pulling if it provides strong leverage. However, for many puppies—especially those that lunge, cough on lead, or have delicate necks—a well-fitted harness can be a sensible choice for day-to-day walking.

Practical balance for many Australian households:

• Use a flat collar primarily for ID tags (where safe)
• Use a well-fitted harness for walking and training
• Consider a safety connector between collar and harness during training if escape risk exists

Training and Behaviour: Why Reviews Should Mention the Human End of the Lead

Harness reviews are incomplete without recognising that lead walking is a skill. Puppies pull for simple reasons: they want to reach smells, people, other dogs, or they are worried and want to leave.

Introducing the harness positively

A calm introduction reduces struggle and future aversion:

• Let the puppy sniff the harness.
• Reward calm interaction.
• Touch the harness to the body, reward.
• Put it on briefly indoors, reward, then remove.
• Increase duration gradually.

This matters because a puppy that fights the harness makes it harder to fit correctly.

When a front-clip helps (and when it does not)

A front-clip can help if:

• Your puppy pulls consistently
• You need extra steering during training
• You pair it with rewards for loose lead walking

It is less helpful if:

• The harness rotates heavily when clipped at the front
• The puppy becomes tangled due to poor lead handling

Recommended Related Products from PetCareShed

The following product categories are commonly useful alongside a puppy harness, particularly when managing growth, comfort, and training. These are framed as practical supports rather than “extras.”

• Adjustable puppy dog harness (dual-clip preferred): Helpful for switching between back-clip for relaxed walking and front-clip for training sessions.
• Double-ended dog lead: Allows front-and-back connection for improved steering and reduced twisting during early training.
• Padded dog collar: Suitable for ID tags and as a secondary safety attachment, provided it fits correctly and does not place pressure on the throat during walking.
• ID tag and tag silencer: Reduces noise irritation for sound-sensitive puppies while supporting identification.
• Training treat pouch: Encourages consistent reward timing during leash training.
• Long line (training lead): Useful for safe exploration and recall training in open areas where permitted.
• Cooling mat and travel water bowl: Particularly relevant for summer outings and car travel.
• Grooming brush and mild pet wipes: Helpful for removing sand, grass, and debris that can contribute to harness rubbing.

Puppy Harness Maintenance in Australian Conditions

Harness maintenance is often overlooked, yet it affects comfort and skin health.

Cleaning frequency

• Weekly if used daily
• Immediately after beach walks or muddy outings
• More often if your puppy has sensitive skin

What to check during maintenance

• Frayed webbing near attachment points
• Loose stitching
• Cracked buckles
• Rust on metal rings
• Stiffness from salt or dirt

A stiff strap can increase rubbing even if fit is correct.

When to Replace a Puppy Harness

Replacement is not always a sign of poor quality. Puppies change.

Replace the harness if:

• You cannot maintain a two-finger fit without the harness sitting incorrectly
• The girth strap consistently migrates into the armpit area
• The puppy’s chest piece sits too high even when adjusted
• Hardware is compromised

For many puppies, one harness may suit early months and another may suit adolescence.

Identification and Legal Basics (Australia)

While this article focuses on harnesses, identification and compliance matter for welfare and for day-to-day life.

Microchipping requirements vary by state and are often tied to sale/transfer and age thresholds. For example, Agriculture Victoria states that dogs must be microchipped before first registration with council. (Source: Agriculture Victoria) https://agriculture.vic.gov.au/livestock-and-animals/animal-welfare-victoria/domestic-animals-act/registration-legislation-and-permits/microchipping-of-dogs-cats-and-horses/microchipping-of-dogs-and-cats

Many councils also have local rules around registration, tags, and leash requirements in public areas. A harness does not replace legal obligations for identification.

FAQ: Dog Harness Reviews in Australia for Puppies

What is the best type of harness for a puppy that is still growing?

A highly adjustable harness with multiple adjustment points is usually the most practical choice. Many owners find an anatomical Y-front style helpful because it can provide shoulder clearance and stable chest positioning when fitted correctly.

How often should a puppy harness be adjusted?

During rapid growth periods, it is sensible to check fit weekly. A practical baseline is to re-check every 2–4 weeks, and immediately after a noticeable growth spurt or weight change.

How tight should a puppy harness be?

A common comfort and safety check is the two flat fingers rule: you should be able to fit two flat fingers between the strap and your puppy’s skin without forcing. This is widely referenced in harness fitting guidance. (Source: RSPCA Pet Insurance) https://rspcapetinsurance.org.au/pet-talk/how-to-choose-the-right-dog-harness/

My puppy keeps scratching or biting the harness. Is it a fit problem?

Not always. It can be a normal adjustment response, particularly in the first week. However, persistent biting or scratching may indicate rubbing near the armpits, buckles contacting skin, or the harness being too loose and shifting. Re-check fit and introduce the harness gradually with rewards.

Can a harness harm a puppy’s shoulders or gait?

A poorly designed or poorly fitted harness can restrict movement, particularly if straps sit across the point of the shoulder or crowd the armpit area. Look for designs that allow free shoulder extension and do a short walk-test in both walking and brief trotting.

Is a front-clip harness safe for puppies?

Generally, a front-clip can be safe when fitted correctly and used with appropriate lead handling. It is often used to reduce pulling leverage. If the harness rotates heavily when clipped at the front, it may cause twisting and rubbing and may not be suitable.

Should puppies walk on a collar or a harness?

Many owners prefer a harness for walking to reduce pressure on the neck, particularly for puppies that lunge or pull. Research discussions note that collars can concentrate force on the neck, while harnesses distribute force differently. (Source: PMC) https://pmc.ncbi.nlm.nih.gov/articles/PMC12036695/

What if my puppy overheats in a harness during summer?

Choose breathable, lightweight materials and avoid heavy padding or full vest coverage in hot weather. Plan walks early or late and keep outings short. Australian summer guidance emphasises breathable designs for heat management. (Source: PetCareShed) https://petcareshed.com.au/blogs/pet-supplies/best-dog-harnesses-for-australian-summers

Are vest harnesses good for small puppies?

They can be comfortable for very small puppies because they spread pressure across a larger surface area. In warm climates, however, the additional coverage can trap heat and moisture. If you choose a vest style, prioritise breathable mesh.

Why does my puppy’s harness suddenly start rubbing when it was fine last month?

This is common during growth spurts. The chest can deepen, the shoulders broaden, and the coat can change. A harness that previously sat behind the armpit may now drift forward, or a strap may become tighter than intended.

How can I reduce the risk of my puppy escaping the harness?

Ensure correct sizing, keep the harness snug, and consider using a safety connection between collar and harness during training. Avoid relying on “escape-proof” claims; instead, focus on fit stability and calm training around startling situations.

How much walking is appropriate for a young puppy?

RSPCA guidance supports short, slow walks for young puppies and building up gradually during growth. (Source: RSPCA Knowledgebase) https://kb.rspca.org.au/categories/companion-animals/dogs/puppies/how-should-i-exercise-my-puppy

Do I need to microchip my puppy in Australia?

Microchipping is a legal requirement across most Australian jurisdictions, with details varying by state and council requirements. For example, in Victoria, microchipping is required before first registration with council. (Source: Agriculture Victoria) https://agriculture.vic.gov.au/livestock-and-animals/animal-welfare-victoria/domestic-animals-act/registration-legislation-and-permits/microchipping-of-dogs-cats-and-horses/microchipping-of-dogs-and-cats

What should I do if my puppy gets a sore spot from a harness?

Stop using the harness until the area has healed, keep the skin clean and dry, and reassess sizing and strap placement. If the skin is broken, the area is swollen, or your puppy is in discomfort, seek veterinary advice.
