Hehe, thanks for the replies ^^ All that I'm really certain of is that she is some kind of a herding dog; her personality, its obvious that herding has been bred into her. The reason I thought ES was because I've seen some pictures of some with the same coloring as her, but I've never actually seen an ES in person and know nothing about the breed. She has a very bad underbite, but I think that could just be a birth defect, since she also has elbow problems and back problems. I can see why you would think boxer, especially based on that picture, but she's pretty small, only about 30 pounds, and her shoulder doesn't even come up to my knee =) But thank you for the opinions ^^ Whatever she is, she's a love.
