hehehehe, our Aussie was maxed out at 90 pounds. Then he lost some weight and got down to 80 pounds. This is because he always managed to eat anything and everything in the house. He wasn't always that big though. Our vet called him morbidly obese. We tried everything, and had him on weight management food. We got him mat 1 year old and I believe he was around 60 pounds then. But, I have yet to see another Aussie that was as big as he was. I think he was a "rare" catch! Lol, I'll try to attach a pic here so you can see him.
