A few years back there was a bill in the NC house that was pretty much wanting the same thing with wormers. It basically read if your dog has worms and you treat him it is in so many words ' performing veterinarian medicine' without being a liscenced veterinarian. The key wording would be in treatment of a known issue vs. preventative.

It never made it anywhere. It was one of those things that I wonder 'there has to be something more important than this'.

Stock up I guess.
