Beemer is a sweet Lab/Aussie mix, just under 2 years old. My wife and I adopted him and his brother as puppies, but my wife has passed away, and I'm not able to provide the attention he needs. He gets nervous and bites when strangers come into the house, but he is fine once they are inside. He also SOUNDS very aggressive with other dogs if there is a fence between them, or he is on a leash. Once he can interact, he is fine with other animals, though he does tend to play a little rough for small dogs.
