Story

Dozer is a neutered male, black/white Mastiff Hi! I'm Dozer! I am deaf! I really don't know how to play. It’s kind of sad. I have a little routine here - I just go in my pen, eat a few bites, drink then run back out for a treat. I like being near my people & will follow you around. I am not interested in playing ball. I really just don't know what to do with myself other than just enjoy life. I am so sweet, according to my foster. So if you don't mind a good-sized velcro dog, I'm your guy! ##2498995##

Romeo

Details

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.

Good with dogs,

Story

Let us introduce you to Lila, formerly Blue from Stanislaus Animal Services. Now she’s living her best life as a resident gentle giant and professional couch potato. This sweet girl is equal parts lover, snuggler, and breeze-catching car ride enthusiast. If you’ve got a couch and a car with windows that roll down halfway… congratulations, you already have two of Lila’s favorite things in life. 🚗💨 With new people, Lila is a polite little introvert. She might play it cool at first, but before long she’ll wander over for the classic “hello, may I sniff your hand and accept a gentle pat?” greeting once you pass her vibe check. She’s still very much a baby in a big dog body, so she’s learning things like crate training and impulse control. Lila truly wants to be good — sometimes her baby brain just gets a little louder than her manners. If she disagrees with being crated you might hear a dramatic protest that could easily earn her an Oscar nomination. Consistency and structure are helping her improve every day. This girl is smart and eager to learn. She’s been doing great with the cats in her foster home (who are basically dog-savvy professionals at this point). If one sprints, her “must chase fast thing” instinct may kick in, but a quick correction brings her right back to reality. Because of this, any home with small animals should plan for slow and thoughtful introductions. Lila is a mastiff mix, which means she’s a big girl with an even bigger heart who will thrive with a confident human to guide her. She can be a little unsure of herself at times, but with leadership and reassurance she settles in beautifully. 📍 Fostered in San Jose, CA

Story

Meet our sweet boy Apollo 🐾 Apollo just turned 2 years old on January 5, 2026. He is a loving, affectionate pup who adores belly rubs and enjoys spending time with his people. Apollo is well-mannered and knows basic commands such as sit, stay, lay down, and shake paws. We are heartbroken to say that we are looking for a new family for Apollo due to circumstances beyond our control—our landlord has required that we rehome him. This decision has not been easy, and our only wish is to find a home that will love and care for him just as much as we do. If you are willing to give Apollo a chance and provide him with a safe, loving forever home, please reach out. He truly deserves a family who will cherish him.

Spayed or Neutered,

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)
