Australian Shepherd

These medium-sized herding dogs are known for their intellect, and they make great family pets. But they still have deep instincts to herd and will do so with everything from animals to kids.

If you’re sedentary, this may not be the pet for you, as the shepherd longs to be active. However, if you love an intellectual and tireless sparring partner, you may have found your new best friend.
