What we do
PetFit tells UK dog owners which size of harness and crate fits their dog, across several brands. You pick a breed, add a measurement if you have one, and we show the size that fits in each brand's own chart. Every breed also has an in-depth guide explaining how to measure and how to check the fit.
Who we are
PetFit is a small, independent UK website. We are not owned by, or paid by, any of the brands or retailers we cover, and brands can't pay to change the sizes we show.
Where our data comes from
- Breed sizes come from the Royal Kennel Club breed standards where they give a height or weight. Where they don't, we use named UK sources such as breed clubs, breed rescues and UK breed guides.
- Chest girth is rarely published for a breed. Where no named source gives it, we show our own working estimate and label it clearly as an estimate, so you know to measure your dog.
- Size charts come from each brand's published chart. We note the date we last checked them, and brands do change their charts.
- Advice on fit, crates and travel comes from sources such as the RSPCA, Dogs Trust, Blue Cross and the Highway Code, and every page lists its sources at the bottom.
We haven't tested the products ourselves, and we don't publish reviews or star ratings. We don't give vet or health advice: where health matters, we point you to your vet.
How we match sizes
We use the same rules every time, on every page and in the size finder. For harnesses, your dog's chest measurement decides the size, with weight as a tie-breaker where a brand gives weight ranges. For crates, we compare your dog's length and sitting height, plus about 10 cm of space, with each crate's length and height. Where breed data is all we have, we show a likely range and ask you to measure.
How PetFit is funded
As an Amazon Associate I earn from qualifying purchases. When you click a "Check price on Amazon" button and buy something, Amazon may pay us a small commission at no extra cost to you. That money keeps the site running. It doesn't change which size we show you, and we don't store or show prices.
