I wouldn't worry about any harm from this homeopathic "remedy". Although you are correct to say that onions can harm dogs, the "remedy" he is suggesting is in a concentration of parts per billion. It would be no more harmful than your dog drinking some water, actually the effects would be identical because that's precisely what he would be doing. There is no proof that homeopathic remedies (why would the call it a remedy and not medicine, hmmmm......) have any efficacy beyond placebo in humans (how effective do you think placebo is in dogs?)
The sad thing is, some people might take this guy's advice instead of taking him to the FREAKING VET!
I think some vets prescribe homeopathic remedies to pet owners to try and pry some more of your hard earned money and some actually believe in that crap. Either way, time to find a new vet.
