Nico: Why do we only give our dog water to drink? How come he can't have milk or juice or soda?
Me: Well, let's think about this. If he were a wild dog, living on his own, what would he have available to drink?
Me: So, water is what his body is used to, and if we start giving him other things it might make him sick.
Nico: And if he were in the wild, he would eat other animals and bones, and that's why you gave him the steak bone last night, right?
