About Heelbrook
Heelbrook sells dog harnesses that clip at the chest, for dogs that pull.
Heelbrook exists because of one uncomfortable finding. In 2021, Shih and colleagues measured leash tension across 52 shelter dogs and found that dogs pulled harder on a back-attachment harness than on a plain collar — peak tension of 16.87 newtons against 6.97. Yet the shelves are full of back-clip harnesses sold under the words “no pull”.
That gap between what a label says and what the mechanics do is why the range is narrow. Two of the three harnesses carry a ring on the chest, built to handle a dog that pulls. The third is a padded vest with a printed name patch; it attaches at the back only, which makes it a comfort and identification harness rather than a no-pull.
What we sell, and to whom
Three harnesses, and the first question decides most of it: does your dog pull?
If it does, the front-clip harness is the one. It attaches at the chest, which is the configuration that measured a reduction in pulling in a 2024 trial of 23 dogs. Sizes S to XL, covering a 43 to 107 cm chest.
If it pulls hard, or you want the heaviest build, the tactical harness carries metal rings front and back in 1050D nylon, with a MOLLE panel for patches. If it does not pull, the personalised harness gives you a padded vest with your dog's name and your phone number printed on both flanks, in six sizes from a 39 cm chest to 101 cm. It attaches at the back, and its own page says so in the first paragraph.
A harness is not training. The equipment changes where the force goes; rewarding a slack leash is what changes the habit. Training a dog to stop pulling covers that part.
Getting in touch
Questions about fit are the ones we can help with most usefully, and the answer almost always starts with a chest measurement. The contact page reaches us directly. For sizing, how to measure a dog covers the method; for fitting, how to put a harness on a dog.
