Well, well... I was looking over the AKC Standards for fun.. and it appears.. he is BOTH!
1-Bat ears qualifies for Frenchie.. and BOY does he have some ears.. I was worried he would never grow into them. LOL.
2-Brindle markings can be either.. the "know-it-all" at the BR Vet said Frenchies are never brindle.. well, they are. :P
3-BT have to have a white streak between the eyes.. and Bailey Man does not..
4-But he is built like a Boston. He isnt stocky like a Frenchie.
I always called him a Boston Mix since all that disussion at the last vet, but apparently my little man is a bit of both. (Was bored here and decided to share)
