Costello is a 1-year-old Malinois mix with a compact build at just around 40 lbs, but don't let his size fool you—he's full of heart. Having spent most of his young life in a shelter alongside his brother, Costello is still learning what the big, exciting world has to offer. He's a very sweet boy with a gentle nature, though he can be a little shy when first meeting new people. Give him a little time and patience, and you'll see his true personality start to shine. One of the best ways to win Costello over is through other dogs—he warms up to them quickly, and they help boost his confidence around people. Costello would do best in a home that understands his need for a little adjustment time and can provide a calm, supportive environment. With consistency, love, and maybe a confident canine companion, he's sure to blossom into a loyal and loving best friend. If you're looking for a kind-hearted pup who just needs a chance to come out of his shell, Costello might be your perfect match.
