Finn is super super cute!! I wouldn't worry too much about his weight right now. It sounds like he is doing fine. Just make sure he is healthy, well fed and well loved, which I know he is . If it helps any my Katie weighed 12 pounds at 12 weeks and she is an Akita which is a large breed dog. I thought she seemed small for her age and maybe she was the runt of the litter. Now at 11 months she is holding steady at 80 pounds! We never thought she would get that big. She is about the right weight for a female akita. We think she may even grow some more over the next year. So try not to worry too much about Finn. He looks like he is going to turn out to be a beauty!
