27. Jack Russel Terrier
A big dog in a little dog’s body, this highly energetic and feisty breed is so full of heart that it often gets into tons of trouble trying to make a hero out of itself. They are smart enough to avoid getting into their owners’ nerves and affectionate enough to keep themselves from being yelled at. They are a sturdy, determined, and tough breed of dogs, practically maintenance free, making them easy to take care of. Jack Russell Terriers are amazing sports dogs, agile and fast, thanks to their small but muscular built.
