I'm probably going to get slammed for this but...
Nothing. There's nothing you could have done. It's not your dog and you really don't know the history there. As much as we don't like some things, some times the best thing you can do is mind your own business and look away. If the dog was at the vet, I doubt it was abused or neglected.
While I'll admit that smacking the dog in the face/head probably isn't a good idea, some of these larger, stronger breeds do need a firm alpha model to keep them under control. In a natural dog pack, the alpha would do the same, albeit with it's teeth instead of a tap on the rump, to get the dog to do what he needed to. |
