What's Up With Jack?

I don't know what is going on with my lab. Jack has been acting so stupid lately. The other day, Lloyd caught Jack shreading his grill cover. Lloyd left the grill cover on the ground and the wind must have blew the cover over to Jack. This morning I found that Jack destroyed my vermont teddy bear's hat. At each event, Carson was watching Jack with a look like "you shouldn't do that, you shouldn't do that." I was angry - I now know how Lloyd felt when he found Jack ruined his grill cover. I guess it was partially our fault for all the damages. Lloyd and I shouldn't left the cover or the bear where Jack could get them. But, oh well.
