i dont get why hes showing his teeth like that. afraid of getting a beating?
Its because the other dog did it and they are both together going to bluff their owner and he cant help but grin and laugh about it when he has to make eye contact. The next day he'll eat the treats and she'll take the fall.
Reminds me of my cat.... I always know when he's guilty... And he does too. Little punk takes one look at me, even if I haven't figured out what bad thing he did this time, and bolts for the bedroom to hide.
