My name is Tate!

My Mom found him through a friend, his fosters were going to put him down and so we went to intercept him the day they were going to do so to save him. We don't know his exact age but we think he's around 1 years old. We've had him for two months now and he's a really sweet dog, obedient and affectionate. He gets along fine with two of our other dogs but doesn't with our third- a 120 lbs Rottie. He's bitten her a couple of times after she growled and barked at him, never bad enough to require vet visits and he's gotten a lot better throughout the months we've had him, but my parents don't have the time to give him the proper training and socialization to get him to the point where he can be trusted around other dogs. He's never shown any aggression towards people and once he lets go of the other dog he's completely submissive and goes limp essentially. We need a home for him ASAP as its not good for him to be around a dog he's scared of.
