Guppy – Senior pup Guppy is such a puppy at heart. He gets all excited and wiggles and talks to you when you take him out for a walk. He loves walking in the grass, all the smells are exciting to him. He’s a good walker, he likes to keep going but he doesn’t pull at all. Guppy was surrendered to us after his only owner died.

He also trots around the play yards at the shelter so if you have a fenced-in yard he would like that but if not walks are his favorite anyway. He’s a very good passenger in the car and likes car rides. He should be the only dog in his home. Although he’s doing well at the shelter he is an older fella and we really would like to see him settled with his very own person or persons.
