The type of dog really depends on the kind of people your parents are. You prob want a dog thats chill, not long haired. Do some research in dog personalities and traits. Maybe you can try to match one up with the type of people your parents are. Smaller dogs are going to be hyper and yappy. A lot of times mutts are super chill. Take a look at the human society every now and again, talk to the volenteers, they are super good at matching people up with dogs.
