It seems you can teach a dog just about anything if he's willing. All you need is some patience and a whole lot of treats. Sit? No problem. Roll over? Piece of cake. Meowing? Um, sure. Griffin the dog has no problem trading in his bark for a meow or two in order to get some kibble. It's a dog eat dog world out there and you do what you have to do, right? Watch and learn, pups. This is how it's done.
