# Benadryl for Dogs — Quick answer

PETHEALTH+ (https://pethealth.org.uk/uk-pet-questions/can-i-give-my-dog-benadryl): Benadryl for Dogs — Quick answer. Yes — most dogs can safely take plain Benadryl (diphenhydramine). The standard dose is about 1 mg per pound of body weight, given 2–3 times a day (every 8–12 hours). A 25-lb dog gets roughly 25 mg per dose. Use only plain diphenhydramine with no other active ingredients, and check with your vet before the first dose.
