That Dog

The key measurement is chest girth, taken with a soft tape around the widest part of the chest just behind the front legs, kept snug but not tight. This figure, not weight or breed, is what the size guide is built around.

The classic no-pull harness has two lead rings, one at the front chest and one on the back, giving a choice of clip point. The Tactical harness adds a third ring further back plus a belly strap, which helps stop a determined dog from backing out and suits a double-ended training lead.

An over-the-head harness slips over the head and clips at the sides, which suits strong dogs and pullers, while a step-in harness lays flat so the dog steps in with its front legs, suiting dogs that dislike anything going over their head. There's also the Easy-On, a hybrid that opens from the side without needing to pass over the head at all.

A front chest ring turns the dog gently back towards the owner when it leans into the lead, so pulling stops being rewarding, but it works alongside training rather than replacing it. It is not a fix on its own for severe pulling, lunging or reactivity, where a local trainer is recommended.

A harness with a sturdy padded grab handle and a wider chest and belly panel supports the body rather than pulling on one point, helping an older or recovering dog up steps, into the car or onto the vet table. Owners are advised to consult a vet or rehab specialist first, since each dog's needs differ.

Orders placed by 5pm on a weekday, excluding bank holidays, leave the same day using Royal Mail 48, with a faster option available at checkout. This means most UK orders are dispatched within hours of being placed.

That Dog offers a free size swap within 60 days for a like-for-like or nearly identical item, decided at the company's discretion. If a refund is wanted instead of a swap, the customer covers return postage unless the item is faulty, in which case the return is free.

The Promise covers a genuine fault in materials or workmanship for five years, and the company will repair, replace or refund the item in that case. It sits on top of UK statutory rights and does not cover everyday wear and tear.

Yes, That Dog is the Official UK Distributor for Truelove, which means buying direct gets genuine stock, the full size and colour range and UK-based support. Harnesses sold cheaply elsewhere are often older versions or grey imports without that backing.

Genuine Truelove harnesses, leads and collars carry a traceable ZAN batch manufacturing code, found on the underbelly of a harness or the inner side of a lead or collar. If there's doubt about a third-party seller, That Dog can confirm whether the stock is genuine.
