Buddy isn't quite 6 months old yet (next week) and he already weighs 65.5 pounds! Our last lab weighed that when he was full grown (he was a little on the small side, but still . . .).
We started obedience class with him last week, and he's coming along. Yesterday we had a couple of friends come over, and he DIDN'T jump on them - YAY! They were both ready to knee him - hard - in the chest, but they didn't even have to. He's still a long way away from being ready to have a kitten in the house though (darn it!).
