Separation anxiety

Somehow we have ended up with a dog that has separation anxiety. He was licking his paw so much that there was no fur on it so I took him to the vet yesterday and she said that he has separation anxiety! I had no idea that dogs could get that. They put one of those cones on his sweet little head (pictures to come) so he can't lick and if it doesn't heal up in two weeks, they want to put him on Prozac! It figures that I would end up with a crazy dog. He hates me now because I was the one that took him to the vet. The biggest problem is that the cone on his head makes him more clingy than he was before. It's a no win situation but he looks cute in his giant blue cone!
