Trixie is a very affectionate, playful girl! I was told she was 3 when I adopted her but she has puppy energy. She needs a lot of space to run around. She loves to play fetch and tug-a-war. She gets along great with other dogs. I haven't had her around many other animals, but she has done ok around my nieces and nephews. She's not aggressive with them at all. She is apprehensive around strangers, she will bark. But once you pet her, you're her best friend!
