Can my dog eat chlorhexidine?
A little.
Diluted, yes — it's the antiseptic vets use on dogs, unlike Dettol. Neat, it irritates skin, and it should stay out of eyes and ears unless your vet says otherwise.
Thinking of giving it?
How much is fineFor rinsing a wound, about 0.05% — roughly 1 part of a 2% solution to 40 parts water, or 1 part Hibiscrub (4%) to 80 parts water, or as the label or your vet says. Never in eyes or ears without a vet's say-so.
WhyIt kills germs without the toxicity of phenol antiseptics like Dettol. Neat, it irritates skin, can damage the surface of the eye, and can harm hearing if it reaches the inner ear through a torn eardrum.
Already ate it?
If they ate itA lick off the skin is nothing to worry about. If they drank it neat, rinse their mouth with water and watch for drooling or vomiting; call your vet if it starts.
