Our pup is on the larger size too (at least for now), and will be 5 months on the 16th and is 94lbs as of today. Some grow fast and atop early...some grow alow and grow longer. Its really hard to say what the right weight is because the "right" weight is different for each pup. But it is fun to look at charts and compare as long as we keep it in perspective. I can remember what Sully was at that age, but I k.ow he was 40lbs at 12 weeks, you can search his growth chart on here under Sullys growth chart if you are intereated. Gorgeous pup!
