They are supposed to be out of the sassy biting stage at 5 months??!! Tonka is 8.5 months and still gets naughty when he's in a playful mood. He is not nearly as bad as he was when he was younger though. He will still come up to you and try to randomly bite your hand or if you put your hand up to pet him he will sometimes try to bite you. He also still gets in the feet biting moods where he will go after your feet. Is this normal? Should we be doing even more to discourage this sassy behavior? haha
