Female Terrier, American Pit Bull/Mix named Trinity available for adoption

Once Trinity warms up to you, which happens fairly quickly, she is very affectionate. She loves to be around people and to lean in for cuddles and pets, and it doesn't take her long to get attached. She loves to play with people too. At the dog park, she would rather follow the person she's with than to explore the park on her own.
Trinity walks great on a leash and rides nicely in the car. She responds well to positive reinforcement and is quite smart. Although she can be slightly nervous when new people enter her space, she does greet people well.
Trinity was born in 2014. Due to a history of aggression toward other dogs, she should be a single dog in a home with no other animals, including cats. She already knows basic training cues such as 'sit' and 'down' and is doing training with Dogtown caregivers to reduce her reactivity to other dogs while on walks. She's also working on crate training and muzzle training. Currently, she eats a prescription diet and takes medication for an enlarged heart.
Trinity will be a great companion in a home where she can someone's one and only. Trinity has a generous sponsor who has covered her adoption fee.
