Chihuahuas are relatively unpretentious dogs, easily getting used to both living in a small apartment and in an elite mansion, but you still have to work on arranging a separate corner for a four-legged newcomer. In particular, the puppy needs to buy a comfortable bed or a house in which he would be able to remain “alone with his own thoughts.” The food bowl must match the dimensions of the animal, as well as the toys purchased for it.
