I remember Sam. I taught him lots of stuff, he used to get tired of it because I would make him think too much and he was just a dog. But one day I told him about money. "With money you can buy things. If you have enuff money you can go to the man and give him the money and he'll give you the bone." He liked that idea, and of course he had already got the concept, I said "you want to see some money?" He said yeah, quite excited because money must be pretty special if the man would give away bones for it, and I showed him some coins from my pocket. He sniffed it in disgust "that's it? Money?".. carried on sniffing the ground. They're so real, not bogged down by any of the silly human rules and customs. If a Pooh smells nice, they sniff it. They know no shame, completely naked and always circumcised of heart.You don't speak dog? No wonder he wont obey you, lol. Dogs speak very efficiently. Mostly body language so you gotta know what to look for.
For example, one time I was sitting there watching tv and my dog comes up to me and sets his empty food bowl in my lap. What did he just say?! I heard him clearly. He said Feed Me. So I did. So look out for that dog bowl.
