Thanks everyone! I knew he was part lab when I inquired about him. When my family went to meet him we were told about the part Newfoundland. Of course by then it was love at first sight, so it looks like we might just have a giant dog!
Awww I have a Newfador too! About the same age! His name is Nintendo (Kids named him haha!) I call him my Baby Giant and our Teddy Bear! His "brother" is a lab/pit/GSD mix and I'm sure he's going to out grow him. I tell him all the time, that Nintendo is gonna be bigger then him someday and he won't be able to pick on him so easily. lol
