This Adopted Pit Bull Now Has A Permanent Smile (12 pics)

Um, in case you're too stupid to know this, which I'm sure you are, animals don't use facial muscles to express happiness.

For example, it could be surmised with equal validity that the dog in these photos is thinking, in its limited capacity:
a) I've got to take a sh*t
b) I'm hungry/thirsty/tired
c) I hate these strange, ugly creatures, but they feed me so I'll tolerate them.

Anthropomorphism - one of the hallmarks of the retard.

Dogs learn and copy humans. My pit bull cross smiles whenever I come back from work. He bares his teeth, as humans do when they smile, he has no aggression and his tail wags furiously. Just learnt that's how we greet each other in my family.

Thus the illusion for which so many fall. Mimicry differs greatly from comprehension and deliberate thought process.

Your dog is not "smiling". He may on some level be happy to see you, but this will show in tail-wagging, not facial expression. When bearing his teeth he is only acting out a learned behavior which has led him to anticipate a reward of some kind, such as verbal praise, a belly rub, or a treat.

When a dog growls at an intruder, is he angry? No, he is showing aggression to ward off a perceived threat. Even limited humanized expressions you may infer, such as guilt-face for peeing on the carpet, are only reactions which relate directly to your response, not their own feelings for the carpet. Anything else would constitute an understanding of right and wrong, which is clearly not the case.

Again, animals do not have the same level of sentience as humans, no matter how sappy you try to phrase it.

If you lock your wife and dog in in a cupboard and open it four hours later.....I'm not saying smiles but one of them will be happy to see you.

Look at the little pup.....
