Say hello to my newest foster dog, Shadow! He is a little over 2 years old and an overall great dog. Has a few problems such as leash pulling and jumping, however. Anyhow, does anyone know what mix he could be? Part border collie is what the shelter was saying. I am thinking border collie/pitbull or rottwieler (because of the head shape)?? Her eyes are a light brown color. any suggestions would be welcomed! ps- sorry for the poor quality pics, need to take more later.
