Lab - nothing, knock on wood.
Airedale - A whole catfish, 2.5 lber, one bite, gone. I thought that was going to be an issue for her sooner than later, it wasnt.
Next was a 1 lb block on cheese followed by a 5 lb bag of grits. 3 days plugged up and swollen like a road kill deer in the summer followed by a yard of white and yellow for 2 straight days as it shot out of her. O joy.
