Story
Meet Sully! Looking for a giant lap dog, BFF, and big drooly shadow who wants to go everywhere with you? Sully might be your guy.Sully is a 6 ish year old Mastiff, 135lbs ish, easy going and sweet as pie. He has one good eye, the 'good eye' had cherry eye repair on it but it may pop out again, otherwise he is doing great. Personality: Sully is a gem! He's the definition of a social butterfly- incredibly friendly and affectionate, just loves being right by his person's side.Things he loves: Car rides, little adventures, walks, just being part of your everyday life. He is very much a 'where are we going?' kind of dog.Potty trainedCrate trainedSully will go into a crate, but it definitely isn't his favorite place to be. He would much rather be hanging out with you.Other dogs: Sully is very social and friendly w/ other friendly dogs. He would likely do well with another chill, friendly dog who matches his easygoing energy.Cats: Sully currently lives well w/ a confident cat. With a proper intro he should do ok living with cats.Kids: Sully is a big guy! He can absolutely knock over small kids. Ideally best w/ older kids comfortable around giants.Quirks: Despite his size, Sully is pretty convinced he is lap-dog sized. He would happily spend his whole day following you around, leaning on you, and being your oversized drooly shadow.Ideal home: Sully would thrive with someone comfortable with giant breeds who understands the importance of keeping a big guy's joints safe and their maintenance and costs. He's already ramp trained for getting in and out of the car and would love someone who wants to bring him along rather than leave him behind. Someone looking for a big goofy bff to tag along for coffee runs, walks, little adventures, and then come home and hang out on the couch. Sully really just wants to be included in life, and honestly, with that big drooly face, it's pretty hard not to include him. All K9ppr dogs are fixed, microchipped, vaccinated etc prior to adoption. #bayareadogrescue #mastiffrescue #corsoPlease note-detailed adoption app required!

Story
Adam is an 80-pound silly, calm and cuddly boy doing so well with his amazing\ foster who says her favorite qualities are his squishy, loveable face, his soft fur, and his smile. Adam walks well on leash and is eager to "sit" for his dinner. He gets along great with other dogs. He is calm, playful and has good manners and is not overly curious about cats. He is low energy but really enjoys going for walks and being let out to run and explore in a fenced area. Adam is protective of his family and property and, with proper introductions, is the most loyal and gentle guy! He needs an adopter who can guide him with boundaries and offer lots of socialization opportunities. Everyone who meets Adam falls in love with him! He's just waiting for the right one who's ready to provide him a stable and loving home. If that's you, please submit an application and a volunteer will be in touch! (HD)
