Simba is considered "senior" at the age of 7 (8 in December) but I don't let him get away with anything, so I haven't gotten any comments. I do cut him some slack (I don't work with him as often as I do the girls) but if I tell him to do something I make sure he does it. He can sometimes get snappy with Kiara or other dogs, and if he does he's corrected right away, every time.
