You should get a Terrier!

Terrier

Although this dog will look at you with loving eyes, a terrier is a feisty foe to other animals. They are solo hunters (great for catching rats) but socially, they are the introverts of the dog-world. They love prowling their territory and. because they're so self-sufficient, you'll have to consider getting a fence to keep it from running away!

Needs: Terriers also like to dig, so you might want to put a digging hole in the backyard. They have an exorbitant amount of energy and you'll need to keep them constantly busy to keep them calm, so if you're a jogger, this dog will be delighted to accompany you and will have you competing for your best time.
