What gorgeous pups. Brindles always have a soft spot in my heart. We went to a rescue center yesterday and there was a boxer/pit mix there. His name was Jingles and he looked exactly like your two here with a shorter muzzle. Except the part that got me was that his two ears were flopped over but erect and went two different ways. I just love'em and I would have taken him home right away if I was allowed. I hope someone gets him soon.
