The size of the dog that you choose is very important. I think that more important than size is breed, because some sizes are actually very lethargic and some small dogs are extremely energetic. You have to realize that if you have a small dog, like a Jack Russell, that dog needs copious amounts of exercise, whereas rescued Greyhounds are couch potatoes. You have to really take into consideration what that dog was bred to do.
