I am a big fan of Cesar Millan - the dog whisperer.
And I understand when he says don't try and make a human out of a dog. Rather give it structure, balance and guidance - the same treatment it would receive in a pack.
But I wonder - do dogs (and other animals) have feelings - human feelings? Do they love, hate, cry, mourn, delight, sulk and possibly hold a grudge?
And can they understand (human) language?
Perhaps we should be careful what we say around animals... just in case they can understand us :-)
Dogs are, after all, man's best friend - I know I've had at least 3 canine best friends in my life. And I am richer for having known them. I hope they felt the same.
