Just looking at Mack's puppy records.....
At 5 months he was 44.9 lbs. At 6 months - 51.5 lbs. But he's a moose, always has been. His Mom and Dad were on the small average size. I think someone slipped a Mastiff into his litter and no one noticed.
He has been as high as 90 lbs (too much) but we try to maintain at about 85 lbs - it's a constant battle with him.
