My name is Millie!

Millie is a 3-year old mix -- we believe Lab and German Shephard -- but she could have other breeds in her. We've had Millie since she was a puppy. She is the sweetest dog and is smart and listens very well. She's very submissive and is a people pleaser. She's been around kids of all ages. The reason we are rehoming her is we've had a few incidences with one of our small dogs (we have 3 other smaller dogs) where Millie is acting aggressively toward her with the last incident resulting in an injury and now she's terrified of Millie. We are heartbroken because Millie is such a good dog. I would recommend her not being with smaller dogs. She has not acted aggressively toward any other dogs besides our one.
