About Our Dog Harnesses
Loved by 30,000+ dog parents across the UK. Every dog deserves a harness that feels as beautiful as it looks. At Bailey & Coco, we design premium dog harnesses that combine thoughtful craftsmanship, ergonomic design, and the kind of style that makes other dog mums stop and ask where you got it.
Our collection is built around one simple idea: your dog should move freely, walk comfortably, and look wonderful doing it. Whether you have a wriggling puppy, a strong puller, or a gentle senior, our adjustable harnesses are designed to give you control without compromising your dog's natural freedom of movement.
We craft every harness with padded straps for comfort, reflective elements for visibility on darker walks, and premium materials that hold up through rain, mud, and endless adventures. Because the best dog harness is one you both love reaching for, every single day.

Trail & Glow Dog Harnesses
Our Trail & Glow range is the harness UK dog owners trust for robust durability and all-day comfort. Every Trail & Glow harness features dual clip points: a front clip for no-pull training that gently redirects your dog's momentum, and a back clip for relaxed everyday walks.
The ergonomic design distributes pressure evenly across your dog's chest and shoulders rather than concentrating force on the neck. That even pressure distribution matters: it protects your dog's throat, reduces strain, and makes walks more comfortable for strong pullers and gentle strollers alike.
Every harness includes reflective elements woven into the straps for visibility on early morning and evening walks, a lockable safety clasp on the neck for secure fitting, and a sturdy top handle for close control when you need it. The adjustable chest strap and neck strap let you fine-tune the fit so it sits snugly without rubbing or restricting movement.
Our materials are chosen for real life, not just the showroom. Quick-drying, weatherproof fabrics mean your harness handles rain, puddles, and beach days without holding odour. The padded straps stay soft against your dog's coat wash after wash. It's the kind of robust durability that means you buy once and trust it for years.
For rainy walks or beach days, pair your Trail & Glow with our waterproof dog leads and waterproof dog collars. They're quick to clean, odour resistant, and made to match.

How to Choose the Right Dog Harness
Choosing the right dog harness comes down to three things: fit, function, and your dog's walking style. Get these right and walks become more enjoyable for both of you.
Fit is everything. A harness that's too loose can let your dog slip out. Too tight and it restricts movement or rubs. Our sizing system is based on two measurements: neck circumference and chest girth. Measure your dog with a soft tape, keeping two fingers of slack beneath the tape for comfort. If your pup falls between sizes, we always recommend sizing up.
Think about how your dog walks. If your dog pulls, a front-clip harness redirects their forward momentum gently to the side, naturally discouraging pulling without any discomfort. If your dog walks calmly, a back-clip gives you a relaxed connection. Our Trail & Glow gives you both options in one harness, so you can switch as your dog's training progresses.
Consider your lifestyle. If you walk in all weathers, prioritise weatherproof, quick-drying materials. If you walk near roads in the dark, reflective elements are essential. If you have a strong dog or walk near livestock, a harness with handle gives you instant close control.
Look for even pressure distribution. The best harnesses spread the load across the chest rather than pulling against the throat. This is gentler on your dog's trachea and more comfortable for extended wear. Our adjustable chest strap ensures the harness sits in the right position for your dog's unique shape.

Types of Dog Harnesses
Understanding the different harness types helps you pick the one that suits your dog best. Here's what you need to know.
- Front-clip harness – The lead attaches at the chest. When your dog pulls, the harness turns them back towards you. Ideal for no-pull training and dogs learning to walk nicely on the lead.
- Back-clip harness – The lead attaches between the shoulders. Comfortable for dogs that already walk well. Gives a natural, relaxed walking position.
- Step-in harness – Your dog steps into the harness and you clip it over the back. Popular for dogs that dislike things going over their head.
- Y-harness – Shaped like a Y across the chest, leaving the shoulders free to move naturally. Excellent for active dogs who need full range of motion.
- H-harness – Two loops connected by a strap across the back, forming an H shape. Simple, adjustable, and works well for most body types.
- No-pull harness – Designed specifically for dogs that pull. Typically uses a front-clip or tightening mechanism to discourage pulling. Browse our no-pull harness collection.
- Padded harness – Features soft padding on the chest plate and straps. Prevents rubbing on short-coated or sensitive dogs. All our Trail & Glow harnesses use padded straps as standard.
- Waterproof harness – Made from quick-drying, weatherproof materials that don't hold moisture or odour. Perfect for UK weather.
Our Trail & Glow combines the best of several types: dual front-clip and back-clip attachment, padded straps, a Y-shaped chest plate for natural freedom of movement, and weatherproof materials. It's one harness that covers almost every walking scenario.
Dog Harness vs Dog Collar
It's one of the most common questions we get, and the honest answer is: most dogs benefit from having both.
When a harness is better: A harness is the safer choice for walking, especially for dogs that pull. Collars concentrate all the force on the neck and throat, which can cause tracheal damage over time, particularly in smaller breeds. A harness distributes that force across the chest and shoulders, protecting your dog's airway and giving you more control with less effort.
Harnesses are also better for puppies learning to walk on the lead, dogs with respiratory conditions (like flat-faced breeds), dogs prone to slipping out of collars, and any dog that pulls even occasionally.
When a collar works well: Collars are ideal for carrying ID tags, quick garden trips, and dogs that walk perfectly at heel with zero pulling. Many owners use a collar for ID and a harness for walks.
For training: A front-clip harness is one of the most effective and humane tools for teaching loose-lead walking. It redirects your dog's momentum without pain or discomfort, making it a far kinder choice than slip leads or choke chains.
We recommend pairing your harness with a matching dog collar for ID tags and a coordinating dog lead for the complete walking setup.
Harnesses by Dog Size
Every dog is shaped differently, even within the same breed. That's why we offer five sizes across our Trail & Glow range, each with generous adjustment on the neck and chest straps. Here's a guide to help you start in the right place.
Puppies and Extra Small dogs – Chihuahuas, Yorkshire Terriers, Toy Poodles, Maltese, and puppies under 5kg. Our XS harness fits necks from 26cm and chests from 26cm. For puppies, read our puppy harness guide for tips on getting the right fit as they grow.
Small dogs – Miniature Dachshunds, Jack Russells, Cavalier King Charles Spaniels, Shih Tzus, and Cockapoos. Our Small fits necks from 30cm and chests from 35cm. See our breed-specific guides for Dachshunds and Cockapoos, or browse our small dog harness guide for more help choosing.
Medium dogs – Cocker Spaniels, Beagles, Border Collies, French Bulldogs, and Whippets. Our Medium fits necks from 35cm and chests from 40cm. This is our most popular size. For flat-faced breeds, see our French Bulldog harness guide for fit tips that protect their airways.
Large dogs – Labradors, Golden Retrievers, Boxers, Dalmatians, and Standard Poodles. Our Large fits necks from 40cm and chests from 55cm. The wider padded straps and sturdy handle give you confident control on every walk. Read our Labrador harness guide for breed-specific sizing advice.
Extra Large dogs – German Shepherds, Rottweilers, Bernese Mountain Dogs, and other large breeds. Our XL fits necks from 55cm and chests from 71cm. Built with the same premium materials and robust durability as every size in the range.
Still unsure? Measure your dog using the size guide below and if you're between sizes, go up. We offer free UK exchanges within 30 days, so there's no risk in trying.
Trail & Glow Size Guide
Grab a soft measuring tape and measure your dog's neck circumference (where the collar sits) and chest girth (the widest part of the ribcage, just behind the front legs). Keep two fingers of slack beneath the tape.
| Size | Neck | Chest | Back Length |
|---|---|---|---|
| Extra Small | 26 – 34 cm | 26 – 40 cm | 18 cm |
| Small | 30 – 45 cm | 35 – 66 cm | 21 cm |
| Medium | 35 – 50 cm | 40 – 71 cm | 25 cm |
| Large | 40 – 60 cm | 55 – 83 cm | 29 cm |
| Extra Large | 55 – 83 cm | 71 – 99 cm | 31 cm |
Between sizes? Size up. Our adjustable straps let you tighten down, but they can't add room. We also offer free UK exchanges within 30 days so you can try with confidence.
Puppy Harnesses
Getting your puppy comfortable in a harness early makes all the difference. Puppies that start walking in a well-fitted harness learn loose-lead skills faster, feel more secure on new adventures, and avoid the neck strain that collars can cause on young, developing bodies.
We offer two options for puppies. Our Glow puppy harness is an ultra-lightweight, streamlined harness designed specifically for very young or tiny puppies who need something soft and minimal while they're still getting used to wearing a harness. For puppies who are a little bigger or growing fast, the Extra Small Trail & Glow gives you the full feature set: dual clips, a top handle, and a wide adjustment range on both the neck and chest straps so it grows with your pup through those rapid early months.
Both options feature padded straps to keep things comfortable for small frames, and a front-clip option for gentle no-pull guidance from the very first walk. The step-in design makes it easy to put on wriggly puppies without forcing anything over their head.
