Your dog groomer can shape your dogs foot either in an oval, a cat-like or a hare-footed shape.
Which one to choose will depend on the breeds standard and the original purpose for that breed.

The oval foot is a combination of the cat-like and the hare foot, and can be found on breeds where both endurance and speed are important. Large feet were developed by breeders for travelling in snow or sand or for swimming. Whereas small feet were bred for dogs travelling in rough and rocky terrain.
