Warren has been overlooked for more than two years, and he’s still waiting in Phoenix, AZ for the right person to give him a shot. He’s a 3-year-old, large Mountain Dog/Rottweiler mix, about 80 pounds, with sharp bicolor and merle markings and a short coat. Warren is all drive and spirit—he thrives on challenging games, obstacle work, long hikes, and will even walk on a treadmill if it keeps his mind busy. If you want a couch potato, he’s not your match. With dogs, he’s friendly, especially with young ones, but a home without cats or small pets is a must—his prey drive is real. Around his people, Warren is deeply loyal and even protective—he needs an adopter who can set clear boundaries and is eager to keep learning alongside him. He’s been trained by a professional and knows all his basic obedience, both on and off-leash. His trainer is committed to teaching Warren’s adopter everything he knows, at no cost, including safe E-collar handling, to set everyone up for success. Warren is house trained, neutered, and his vaccinations are current. Warren is available to adopt directly or as a foster-to-adopt. If you’re strong, committed, and ready for an active partner, Warren could be your guy. They are waiting with paws crossed! Apply now!
