Story

08/19/26 15:27Gnocchi has been placed on needs rescue URGENT for his consistent high FAS (fear, anxiety, stress) score since begin here at the shelter.Gnocchi is a handsome 7 year old mastiff that has been in the shelter since June. When he first got here, his behavior was very inconsistent. Some days he would be loose and happy to greet people at the front of his kennel and other times he was barring teeth. Now that Gnocchi has had time to decompress, he is not showing any signs of aggression towards people or other dogs. In the kennel now, he is constantly barking and jumping. Gnocchi knows that the kennel life is not for him and he tells us that every time he returns from his walks. He is always super happy to leave the kennel for his daily walk, but he is known to stall when it is time to return. And who can blame him. He wants a life outside of the kennel with someone who will give him all the love he deserves. Will you be the one to help this sweet boy and give him a home away from the shelter?

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.

Romeo

Mastiff

Male, 7 yrs 4 mos

Palo Alto, CA

Size

(when grown) X-Large 101 lbs (46 kg) or more

Details

Not good with dogs, Not good with cats, Needs experienced adopter, House-trained, Spayed or Neutered, Shots are up-to-date,

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.
