Costello is a 1½-year-old Staffordshire Terrier mix who came to the shelter as a stray with his brother, Abbott. While we’re still getting to know him, one thing is already very clear — Costello knows how to turn on the charm. This sweet, affectionate boy loves being petted and is generous with kisses. He enjoys human attention and soaks up every bit of love he can get. Costello has a friendly, endearing personality that makes it hard not to fall for him. We haven’t had the chance to dog test Costello yet, but with the right meet-and-greet, he may do well with a dog friend. If you’re looking for a young pup with a loving heart, playful potential, and plenty of kisses to give, Costello might be your perfect match.
