I have a BullMastif mixed with an Olde Bulldog. She is always being mistaken for a boxer. She's a brindle which is funny because neither of the parents are brindle. I think that's why she is mistaken for a Boxer. She has a barrel belly but I think she'll grow into it. If I could put a pic on the website I would show you. To sum it up she's a cutie. She has a good disposition as well. Very laid back dog.
