How long can a pitbull puppy and a chihuahua mix puppy stay in the same crate? Dog Breed Discussions
If they are around each other from an early age, they will get used to being together quickly. Since both of them are puppies it's not a problem for now. They have different behavioral personalities and there is a difference in size. They may get along well because they are still puppies and if you train them they will get along. Problem will be in the future when they are bigger, that the pitbull can easily hurt the chihuahua because she is so small and fragile. Get another crate and put it close to the other crate. This way they will be close but will have their own space.
