Older lab weighs about 82 pounds, she is a tank, all muscle. I always laugh when we go to the vet, if a new tech takes her, I say, be careful she is really strong, and they sort of look at me like, yea, sure lady, she's 11! Then they come back and say, wow, she is really strong! :rotfl;
2 yo lab is 67 pounds. She is an English lab from a different breeder and is is great shape. Very different body type from our old girl, longer and lean.
7 yo terrier-ish rescue is 17 pounds and she rules the roost!

If one of the big girls has a bone or toy she wants, she just walks right up and takes it. One of our favorite stories is from around 18 months ago. Our younger lab was about 6 months and decided that she was all that and a bag of chips! Furthermore, since she was a "big girl" now, she could take what she wanted. Well Sweetie had about enough of that after five minutes. All the the sudden, she growled, snapped and said something in dog and bam, Haley was sitting in the corner, all contrite and well behaved!



We tried to figure out how she did it!
