So this is my first post, and I'm not sure if this is in the correct category, but I just had a random question-and any input would be great. I was wondering when dogs stop growing. Researching, I read around 18 months. But my chocolate lab seems to not be getting any bigger-he's 6 months old, at about 40 pounds. I also have a yellow lab, and looking back at pictures when he was 6 months old Patton seemed much bigger. I know I see him everyday, so that probably makes a difference. When I send my husband pictures of the dogs (he's in iraq) he tells me that he can tell he is getting bigger. I think he is going to be a smaller lab to begin with-his mom is a black lab, and she is only about 55-60 pounds. I was just wondering when to expect him to reach full growth!?
