How to Choose the Best Harness for a Small Dog

Small dogs might take up less space, but they still need a harness that delivers on comfort, security, and everyday wearability. The best harness for small dogs should be lightweight, properly fitted, easy to adjust, and designed around the unique needs of smaller breeds.

Whether you have a tiny companion who joins you on city walks, coffee hopping around Bondi trips, or everyday runs to the post office, the right harness can make every outing more comfortable... and yes, it can look good too.

We believe dog accessories should be MORE than functional. Your dog’s harness is part of their everyday look, so it should feel as good as it looks.

Why Small Dogs Need a Different Type of Harness

Small dogs often have different body shapes compared to larger breeds. They may have narrower chests, delicate necks, shorter legs, or unique proportions that make finding the right fit more important.

A well-designed small dog harness can help:

• Reduce pressure around the neck
• Provide more control during walks
• Prevent slipping or backing out
• Make walks more comfortable for smaller breeds
• Create a safer alternative to relying only on a collar

The goal isn’t just finding a “small” harness - it’s finding one designed to properly support your dog’s body.

What Makes the Best Harness for Small Dogs?

1. A Secure, Comfortable Fit

The most important factor when choosing a harness is fit.

A good harness should sit comfortably around your dog’s chest without restricting movement. You should be able to fit two fingers between the harness and your dog’s body, but it shouldn’t be loose enough to slide around.

Signs your harness fits correctly:

✓ Your dog can walk, run, and move naturally
✓ The harness doesn’t rub under the legs
✓ It stays in place during walks
✓ Your dog isn’t trying to scratch or remove it

For small dogs, adjustability is especially important because even small differences in sizing can affect comfort.

Check out our harness size guide and remember to go by CHEST measurements when sizing for a harness.

2. Lightweight Materials

A heavy or bulky harness can feel uncomfortable for any dog, but especially for smaller dogs.

The best harnesses for small dogs are made with materials that provide durability without unnecessary weight.

Look for:

• Soft but strong fabrics
• Lightweight hardware
• Smooth edges
• Comfortable chest support

Small dogs should feel like they’re wearing a harness - not carrying one.

3. A Design That Matches Their Lifestyle

Small dogs often have biiiiig personalities.

From daily walks to weekend adventures, the best harness should suit how your doggo lives.

Our harnesses come in a range of beautiful colours to match your dog's unique personality.

From ruby red and bottle green for the festive season, to powder blue or marshmallow if you're welcoming a new pup home and want them dressed for the occasion.

Also, consider additional accessories to match - like a matching lead or poop bag holder. A lot of dog parents are choosing harnesses for style based on these factors. 

The harness walk set includes a harness, in your selected size, a matching lead and poop bag holder. Check out the range!

Harness vs Collar for Small Dogs

Many small dog owners wonder whether a harness is better than a collar for their pooch.

And it's a great question, with a pretty simple answer: While collars can work well for identification and some everyday needs, harnesses distribute pressure across the chest rather than placing it all around the neck.

This is an essential factor. Especially for smaller breeds, such as Yorkshire Terriers, breeders recommend a harness for added support on the chest - rather than the pressure only applying to their delicate neck if they are pulling.

Small breeds have smaller bones in the neck area, and these can be especially fragile.

For this very reason, we have designed our harnesses with a LARGER neck area. This means the neck loop sits LOWER on the dog's neck - at the base of the neck where the chest begins. It relieves tension against the more delicate part of the neck if they pull!

A harness can also give you better control during walks, especially if your little dog is confident enough to think they’re much bigger than they actually are...let's be honest, this is generally the case!

How to Choose the Right Size Harness for a Small Dog

Sizing by weight alone isn’t always accurate.

The best way to find the right size is to measure your dog’s:

Chest girth:
Measure around the widest part of your dog’s chest, usually just behind the front legs. Put two fingers between the tape measure and the chest to ensure the fit is not too tight.

Weight:
Use weight as a guide, but prioritise chest measurements.

Every dog has a different shape - a miniature Dachshund vs a standard Dachshund will need completely different fits and it can be very tricky to go by weight alone, as the weight is distributed very differently depending on the breed - and even the individual dog. 

Style Matters: The Rise of Fashion Dog Accessories

Dog accessories have become an extension of personal style.

Today’s dog owners want products that are functional but also fit seamlessly into their lifestyle... whether that means matching their home aesthetic, their wardrobe, or their dog’s personality.

A thoughtfully designed harness can become an everyday essential:

• Minimal and modern like the cocoa harness
• Playful and colourful like the marshmallow harness
• Premium and elevated like our burgundy harness
• Designed for everyday wear like our cream harness

We create dog accessories for owners who don’t want to compromise between style and function.

Because your dog’s harness is something they wear every single day - it should be something you actually love seeing them in.

Final Thoughts: Finding the Best Harness for Your Small Dog

The best harness for small dogs combines three things:

Comfort. Your dog should be able to move freely.
Fit. It should stay secure without rubbing or restricting.
Style. It should feel like it belongs with your dog’s personality.

The RSPCA recommends "introducing the harness gradually and gradually increasing how long they wear it", if you notice that your dog seems anxious wearing their harness for the first time.

The right harness should make walks easier, safer, and more enjoyable - while giving your small dog the everyday look they deserve.
