Why does there seem to be so many old poker chips with dogs on them, even dogs playing cards. I've also seen an old picture of dogs sitting around a table playing poker. Is there a connection here I don't see......I did hear a story once about a guy who taught his dog to play poker. He was real good at playing his cards and reading the other players. It didn't work out though, because every time he got a good hand he would wag his tail.
