I completely get that, and having done the training you would have gone through the finer points, but as a member of the public I AM searching and can't find it. I've read the box, the instructions, the safety data sheets and the distributors website. If its that illegal, it needs to be stated somewhere. For use only on dogs, carries the implication of dont use it on cats or horses, given the context of the rest of the information on the packaging.
