This was Duke. He’s unfortunately long gone, but he was a good dog. He was the first dog I got as an adult, but really he was my then girlfriend’s, now wife’s dog. Still, hopefully this clip shows that he loved me as well, at least when she wasn’t around.
You know it.
My wife used to call him “Pook” or “Pork Chop” alongside his actual name.
He responded to any of them.
I know a dog named Duke (who honestly resembles your’s a lot). He gets called “Dork” a lot and he loves it.
