Meet Stacks. Stacks is as solid as his name: lean with muscle, energy for days, and a surprising amount of heart. His smile grabs you, and his wide-eyed curiosity is almost contagious. At about 2 years old and weighing in at 57 pounds, Stacks is built for play, not for life in a kennel. The shelter environment can stifle his spirit and put him on edge, but get him outside and he starts to relax. Give him a yard, and he'll tear around with zoomies and goofy antics until he's ready to flop down for love. He's gentle with treats, obsessed with fetch, and happiest when playing with confident female dogs who bring out his best. Stacks isn’t rough or rude—he just asks for patience, space to shake off the stress, and someone who sees the sweet, funny personality beneath the big exterior. The shelter doesn't let him be his full self. Stacks shines brightest where he can decompress and be included. Someone willing to invest the time will find a loyal, entertaining companion in Stacks.
