If they are doggie chocolate treats, they are probably o.k. If not, no way. Real chocolate can make them very sick. The doggie treats are not made with real chocolate, but with something called "carob flavor", which is an imitation chocolate flavor.
They're ok as far as I know. I used to get them for dogs we had in the past and they loved them. I will have to look for them for Angel... I haven't thought about them in a long time. Thanks for the reminder!
