Quick Answer: The best dog harness in the UK distributes pressure across the chest and shoulders rather than the neck, making walks safer and more comfortable for your dog. Front-clip harnesses discourage pulling, back-clip harnesses suit well-trained dogs, and dual-clip harnesses offer both options. For brachycephalic breeds (Bulldogs, Pugs), a harness is essential as collars can restrict already-compromised airways.
At a Glance
- Front-clip: Best for pullers — redirects forward momentum sideways
- Back-clip: Best for trained dogs — comfortable, no pulling correction
- Dual-clip: Both options — versatile for training and casual walks
- Step-in: Best for head-shy dogs who dislike things going over their head
- Must-have for: Pugs, Bulldogs, Frenchies, and all flat-faced breeds
- Sizing: Measure chest girth (widest point behind front legs)

Harness vs Collar: Which Is Better?
For most dogs, a harness is safer than a collar for walking. Collars concentrate all leash pressure on the neck, which can cause tracheal damage (especially in small breeds), exacerbate breathing difficulties in brachycephalic breeds, and potentially cause cervical spine issues in dogs that pull heavily.
Harnesses distribute pressure across the chest and shoulders, providing better control with less risk of injury. They are particularly important for puppies (who have not yet learned loose-lead walking), breeds with delicate tracheas (Yorkies, Pomeranians, Chihuahuas), flat-faced breeds, and any dog that pulls.
Collars are still useful for carrying ID tags and for well-trained dogs on gentle walks. Many owners use both — a harness for the lead and a collar for ID tags.

How to Measure and Fit a Harness
- Measure chest girth. Wrap a tape measure around the widest part of your dog’s chest, just behind the front legs. This is the most important measurement
- Check neck measurement if the harness has a neck strap — measure where a collar would sit
- Allow two fingers between the harness and your dog’s body at every point. Too tight causes chafing; too loose allows escape
- Check for rubbing. After the first walk, check armpits and chest for red marks or fur loss — signs of poor fit or chafing
- Adjust all straps until the harness sits flat against the body without twisting or riding up
Frequently Asked Questions
Do harnesses encourage pulling?
Back-clip harnesses can make pulling more comfortable (which some argue encourages it). Front-clip harnesses actively discourage pulling by redirecting forward momentum. For dogs learning loose-lead walking, a front-clip or dual-clip harness combined with positive reinforcement training is the most effective approach.
Can my dog wear a harness all day?
Not recommended. Prolonged harness wearing can cause chafing, restrict natural movement, and mat fur (especially in long-coated breeds). Put the harness on for walks and remove it at home. If your dog needs something on all day for ID tags, use a lightweight flat collar.
My dog escapes from harnesses — what can I do?
Dogs escape harnesses by backing out of them — usually because the fit is too loose around the chest. Tighten the girth strap until you can only fit two fingers underneath. For persistent escape artists, consider a three-point harness or a PerfectFit modular harness with a secure fit across belly, chest, and shoulders.
