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 âÂÂgood eyeâÂÂ had cherry eye repair on it but it may pop out again, otherwise he is doing great. Personality: Sully is a gem! HeâÂÂs the definition of a social butterfly- incredibly friendly and affectionate, just loves being right by his personâÂÂs side.Things he loves: Car rides, little adventures, walks, just being part of your everyday life. He is very much a âÂÂwhere are we going?âÂÂ kind of dog.Potty trainedCrate trainedSully will go into a crate, but it definitely isnâÂÂt 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 guyâÂÂs joints safe and their maintenance and costs. HeâÂÂs 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, itâÂÂs 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)

Story

Meet Percy! A Puppy Is a Big Commitment — Especially This One! Percy is an adorable puppy looking for a family who is ready for all the fun, love, and responsibility that comes with raising a puppy! While he's little now, don't let his puppy size fool you. Mom weighs approximately 65 pounds, and Dad is estimated to weigh around 170 pounds, so Percy is expected to grow into a very large dog! Raising a puppy takes time, patience, consistency, and commitment. Early training and socialization are absolutely essential. Percy will need continued exposure to a variety of people, places, sounds, experiences, and other friendly, well-socialized dogs to help him grow into a confident, well-adjusted adult. Basic obedience training, leash manners, house training, and learning appropriate behaviors should all be part of his daily routine. Puppy training classes and ongoing positive reinforcement are strongly encouraged. Percy is not suited for a home where he will be left alone for long stretches of time. He needs companionship, supervision, and interaction throughout the day and should not be left home alone for more than three hours at a time while he is young. And remember, the cute little puppy you bring home will eventually become a very large adult dog! His future family should be prepared for the exercise, training, space, and lifelong commitment that comes with owning a giant-breed dog. If you're ready to invest the time and effort into raising a puppy and helping him become the wonderful adult dog he's meant to be, Percy could be a very rewarding addition to your family!
