You should look at a Newfoundland instead if you want size with lab type behavior. Labs can get large, I currently have a 130 lb male, and I had an even larger one before, but it isn't normal. If you find a breeder that has a large male and large female, you are likely to get large puppies. However, since the breed standard is less than 80 lb, you won't find many quality breeders doing this on purpose. The bigger dogs have more hip problems and in general more health issues, so keep that in mind.
