I had to give my dog some orally as an emergency home-administered emetic. The vet gave me instructions for concentration and volume. It bubbles in the stomach and makes the dog throw up but can cause irritation and some other problems.
But inhaling it? Sheesh. I guess some covidiots still have that idea that they could use something to disinfect inside the body. You'd think the bleach and light BS would tip them off to stop trying hack-hick remedies, but no.
