Can I Give My Dog household 3% ONLY?
Yes, with care
Hydrogen peroxide 3% (emergency vomiting induction) is commonly referenced for dogs at published doses. Published guidance for dogs: 1 mL per lb (2.2 mL/kg), max 45 mL, ONE repeat after 10-15 min if no vomiting, once (one repeat max). ONLY when a vet or poison control ON THE PHONE tells you to. Wrong situations (caustics, sharp objects, breathing problems, brachycephalic breeds) make things worse. Call first: Pet Poison Helpline 855-764-7661.

The safe habit
Confirm any medication decision with your veterinarian, who knows your dog's health history and other medications. VetDose shows published reference data, not prescriptions.
