Story
Rosco is a loving, affectionate dog looking for his perfect forever home. I adopted him from the San Jose Animal Center about two years ago when he was just 6 months old, and he’s now around 2–3 years old. Unfortunately, I don’t have the time or resources to give him the attention and training he deserves, so I’m hoping to find someone who can. Rosco is a gentle, clumsy giant with a heart of gold. He’s very sweet and docile and loves being close to his people. Rosco is crate trained and knows several commands, including sit, down, place, stay, and go eat. He would thrive in a home with a yard or outdoor space where he can stretch his legs and go to the bathroom easily. I’ll include his crate if needed.

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.
