How to measure your dog for a collar
A collar that's too tight is uncomfortable, and one that's too loose can slip off, taking your dog's ID with it. Here's how to measure and check the fit, using Battersea's advice.
3 steps to the right size
Measure the neck
Use a soft tape measure around your dog's neck, where the collar will sit. If you don't have one, use a piece of string and measure it against a ruler.
Compare with the size guide
Check the measurement against the size guide for the collar you're buying. Every PawTrak collar page has a size guide link next to the size options.
Check the fit once it's on
Battersea's rule: you should be able to slide two fingers between the collar and your dog's neck. Snug, but not tight, and not so loose it could slip over their head.
Keep checking
- Check the fit regularly, especially for puppies and dogs who are gaining weight, as they can outgrow a collar quickly
- Make sure it hasn't loosened over time
- Replace a collar that's damaged or worn
Collar or harness?
Many dogs walk on a harness, but by law a dog in a public place must still wear a collar with your name and address on it or on an attached tag. See our dog ID tag law guide. New to collars? See how to get a puppy used to a collar and lead.
