We have a nearly 5 mo old puppy (Boomer) whom we've had for 3 days now. The previous owners claimed he is pure bred boxer but the odd thing is he doesn't seem to have the black mask fawn boxers should have. Do you think he is mixed with something? Or maybe poorly bred? It was a little concerning to me that they had gotten Boomer from the breeders at 5 weeks old - so young! Which led me to think the breeders couldn't be too reputable to allow someone to take a puppy at that age. Here are a couple pics of Boomer: http://i1192.photobucket.com/albums/aa332/bespoke_designs/3b719340.jpg http://i1192.photobucket.com/albums/aa332/bespoke_designs/b99febaf.jpg Sorry the second one is slightly blurry - he doesn't sit still for long! Either way, we love him already. It just would be nice to know whether to answer "boxer" or "boxer mix" when asked what breed he is!
