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
Sammy is a mini-mastiff at ~60 lbs. He has 1 eye and a semi-lame left front leg, but none of this stops him from getting around and loving life. Though he has limited mobility he can go on short walks and loves to ride in his cart. He is house broken and crate trained. He gets along well with our other 2 dogs, and with all other dogs he has met. He takes a minute to get to know people, but once he does he loves attention and to cuddle! He is a happy guy who would make a perfect cuddle-buddy for someone who doesn't want a highly active dog. He'd do well with another dog or as an only dog.
