BLUTO

Mastiff

Male, 1 yr 3 mos
Pt. Richmond, CA
Size
(when grown) -

Not good with kids, Not good with dogs, Not good with cats,
Story
Bluto is a confident, playful and affectionate boy with a heart as big as his 70-pound, all-muscle frame! He’s house trained and knows how to sit, and while he walks pretty well on leash, his fabulous foster is working with him on not pulling when something exciting grabs his attention. Bluto is a total lovebug adores being around people. He would happily cuddle up with you on the couch any chance he gets. He’s gentle when taking treats and doesn’t mind having his paws handled—making grooming and vet visits a breeze. He loves meeting new people and greets guests in the home with full body wiggles. So far in foster, he has done great with other large dogs who have calm demeanors. When playful dogs approach, he's eager to get involved but he's not quite sure exactly what to do. He takes human or dog direction well though, and will be a playful companion in no time! As he's a large boy who's still learning how to keep all four paws on the ground when he's excited, he would be best in a home with adults only or older kids. He means absolutely no harm, but could easily knock over small kids or anyone unsteady on their feet while he's working on this. If you’re looking for a strong, confident, and affectionate companion who just needs a little polishing, Bluto might be your perfect match, apply today to find out!
