Story

Romeo is very sweet 6 year old boy but the vets think he may be younger. He would love to be a family dog and definitely wants to find his forever home, but can be protective of his people and his space. That being said once he knows you are part of the family he listens very well and knows many commands, sit, stay, down, shake, wait. He is slow to warm up to new people but once he has been introduced to you he is a gentle giant and big couch potato that loves to cuddle. He also really enjoys going for a ride in the car. It is not recommended to have young kids due to his size. He is good on the leash and knows many commands but needs someone that is not afraid of his size and can properly handle him. Experienced adopter with larger breeds is a must. No other dogs or animals in the household and not a good candidate for crates.

Story

His birthday is December 22, 2025. He is a Mastiff × Doberman × American Staffordshire Terrier mix. He is a wonderful, loving puppy who is great with people and other dogs, but he does need a lot of attention and has some separation anxiety.He had parvo as a puppy but was treated and fully recovered. He is healthy now, but he does need his parvo booster shot one last time We absolutely love him and this is a very difficult decision. Unfortunately, I’m moving and starting college, and I’m no longer able to give him the time, attention, and care he deserves. We just want to find him a loving home where he will be happy, cared for, and given the attention he needs

Story

Gus is a 4.5 year old mastiff/rotweiler mix. He a wonderful companion animal and has given our family loyalty, cuddles, and goofiness. He is a low-energy dog who loves to snooze, but also enjoys moderate walks and hikes. Gus needs a new home because he can aggressively resource guard random objects (e.g. a child's toy or a kleenex). We cannot keep him in our house with three very small children who may be inclined to follow him if he takes a forbidden toy. Gus would be great in an adult-only home or a family with older children who can understand and manage this behavior. Gus is great with kids, adults, and other dogs. He is trained on the basics and walks well on a leash. He is neutered and up to date on all vaccinations. It is with an extremely heavy heart that we have to find a new home for this loving dog. But he will be a fantastic addition to any home without small children who wants a loving companion and can manage his occasional resource guarding.

Good with dogs, Spayed or Neutered,

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
