sometimes ppl think that timber is vicious cuz shes very submissive and bares her teeth in greeting...i remember when the ppl just moved downstairs and the guy called timber and then all of a sudden i heard the girl call me, and say, "is your dog mean or does she smile?"
leather bares her teeth when shes very fed up with something lol
my other dogs dont smile unless they are growling haha...not like my other dogs dont growl, but you know what i mean
