When I start working, my parents want to get me a dog. I'll pay for the food and grooming, and they'll pay for the dog and the vet bills. The only stipulation to that is the dog must need at least a half hour of exercise. I was thinking about either a Yorkie or a Maltese. (I want a small dog, because I live in an apartment, and I want one that gets along with cats.) For those of you who have either, how much exercise do they really need?
