【SIZE TIPS】You need dog boots that are just a little bigger than your dog's paw size, but snug enough that he doesn't slide around in them. Measure your dog's paw by having him stand on a piece of paper and press gently on the top of the paw. This will let you see the dimensions of his paw while walking. Trace the paw or mark where the sides and front and back hit so you can get an accurate measurement. You can then match these dimensions to the size guide on the dog boots you want to purchase.
