Story

We got Dutch from a foster home a few years ago and our family has grown, and moved, and grown, and moved. We love Dutch but he’s not getting the care and attention he deserves, we leave all day for work and then immediately have sports in the evenings which means Dutch is outside alone all day by himself. he’s very social and sweet and loves walks. His hips have been achy lately but he still loves to play and walk. He’s a big guy but doesn’t jump up or act overly rambunctious! Great teeth and coat! He hardly barks, unless someone unfamiliar is approaching the house so he’s great as a guard dog, but he might just lick them to death if they get too close! He’s very friendly with people and knows how to be gentle with food and toys. He does like to power chew so he needs heavy duty toys!

BLUTO

Mastiff

Male, 1 yr 4 mos

Pt. Richmond, CA

Size

(when grown) -

Details

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!

Story

Rambo is a wonderful 5-year old Boxer Mastiff mix looking for his forever home. He is a very well-behaved and loyal companion with lots of desire to play outside with other dogs. He was rescued being blind on his left eye, but that does not stop him from being full of personality and spunk. Rambo has been neutered, microchipped, and all if his vaccinations are up to date. He would be a great addition to any family looking for a large dog, preferably in a household without small pets or cats. He weighs about 60 pounds. Please contact me to set up a meet and greet or if you have any questions.
