Why do gray wolves have only four toes on back paws?

Gray wolves actually have five toes on both their front and back paws.

It sounds like you might be thinking of another animal. Perhaps you are thinking of a deer? Deer have four toes on their back paws, but five on their front paws.

Here is a little more about wolf paws:

* Five toes: They have five toes on each paw, but the fifth toe is quite small and doesn't touch the ground when they walk.

* Pads: The bottom of their paws are covered in thick, tough pads that provide traction and cushion.

* Claws: Their claws are non-retractable, which means they can't pull them back into their paws. This helps them get a good grip on the ground when running and hunting.
