Can snakes eat dog food

When hungry, snakes will eat just about any food : birds, frogs, mice, and other dead mammals. Only a large or venomous snake could kill an adult dog, and few would be able to eat one, except to feed on a carcass.

Snakes eat dogs because they can. For a snake, there is no difference between types of prey. A snake will eat whatever it can overpower and swallow.
