Well, he's definatly not a Flemish (the ears would be bigger, and so would his bone structure) but he could be a New Zealand. I don't know really what that breed looks like. He's very cute, though!I'm going to have to say a white Flemish Giant or a New Zealand White, but I'm no expert Very cute!
I would definitely need the weight on him. To me he looks like a Florida White however, there are a lot of breeds that have Ruby-Eyed White as a variety.
Definitely not flemish...the ears aren't right....I'm guessing New Zealand from the way he fits in the harness (he looks bigger to me than a Florida White) but I could be wrong..
