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

Lila is a beautiful Mastiff mix living her best life as our resident gentle giant and professional couch potato while she waits for her forever home 💛 This sweet girl is equal parts lover, snuggler, and car-ride breeze enthusiast. If you have a couch and a car window that rolls down halfway… congratulations, you already have two of Lila’s favorite things. With new people, Lila is a polite little introvert in a big dog body. She may play it cool at first, but once you pass her vibe check, she’ll wander over for a hand sniff and some gentle pets. Lila is still very much a baby brain inside a giant body, so she’s working on crate training, impulse control, and remembering that manners matter. She truly wants to be good… sometimes her dramatic side just makes a guest appearance. Structure, consistency, and a confident human are helping her improve every day. Lila is a mastiff mix, which means she’s a big girl with an even bigger heart. She can be a little unsure of herself at times, but with confident leadership and reassurance she settles in beautifully and bonds deeply with her people. Because of her size, puppy energy, and chase instincts, Lila is looking for a home without small children or small animals. 📍 Fostered in San Jose, CA Apply to adopt Lila: www.cabullyrescue.org/adopt

MEET KATE! A LITTLE SHY, A LOT SILLY, AND 100% WORTH GETTING TO KNOW! 💕 Kate is the kind of girl who may take a minute to warm up… but once she decides you’re safe, congratulations—you’ve officially been chosen. 🥹 ❤️ And Kate does NOT take her job as your loyal sidekick lightly! This beautiful girl is still growing into her body and outgrowing her puppy stage, which means she’s got a little bit of awkward teenager energy going on. 😂 She may initially be reserved in new situations, but give her a little time and her silly, happy personality comes bursting out. Once she trusts you, she is incredibly affectionate, devoted, and will happily follow her favorite human from room to room like a furry little security detail. 👀 🚗 Road trip queen: Kate travels like a DREAM. Most of the time you’ll find her curled up in a little ball, snoozing away while you run errands. Basically, she’s the perfect passenger and has already mastered the art of “Are we there yet?” by simply sleeping through the entire trip. 😂 🐶 Dog social butterfly: Kate has been great with small dogs, big dogs, and groups of dogs! She has excellent doggy social skills and quickly figures out who wants to PLAY. She loves a good game of chase, being chased, and the occasional friendly boxing match. 🥊😂 She can play a little rough, though, so her ideal doggy friends will appreciate her enthusiastic wrestling style. And when playtime is over? She LOVES snuggling up next to another dog for a cozy nap. 🥰 👨 Men: Kate can be a little unsure around men at first, but she has made wonderful progress in her foster home and has learned that the boys aren't so scary after all. She just needs someone willing to let her build that confidence at her own pace. 🐦 Cats & critters: Kate hasn't shown any prey drive and doesn't bother the foster home's pet birds, but she hasn't been tested living with cats yet. 🏡 Home life: Kate sleeps peacefully in her crate all night and even puts herself to bed! She knows when it's bedtime and happily heads into her crate on her own⭐️ Appy to adopt Kate! www.cabullyrescue.org/adopt Fostered in Los Gatos 1-2 years old 65-70lbs

Good with dogs, House-trained,

Story

This stunning Mastiff mix came to the Oakdale Animal Shelter after being heartbreakingly dumped skinny, scared, and suffering from painful ear issues. Winona is around 5–6 years old and everything we love about the Mastiff breed. She can be nervous and skittish at first, but once she knows she’s safe, she is incredibly loyal, loving, and devoted 🥹❤️ Winona is a calm, quiet girl who is wonderful in her crate, loves affection, and is very food motivated. She isn’t looking for a wild, busy life she just wants a safe, peaceful home and someone she can trust. She is good with other calm and neutral dogs, she’s not looking to be playful at this time. 📍 Winona is currently in Oakdale, CA and would LOVE a foster-to-adopt home or an adopter ideally with someone familiar with Mastiffs and willing to give her the time she needs to settle in and show you who she really is. 🏡 You were discarded once, sweet girl. Never again Winona. You deserve the very best. 🥹❤️
