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.

Cats are different

Do not carry this answer over to your cat: for cats, Hydrogen peroxide 3% (emergency vomiting induction) falls under “do not give at home.” Species handle drugs differently, and the dog answer on this page applies to dogs only.

About Hydrogen peroxide 3% (emergency vomiting induction)

Hydrogen peroxide 3% (emergency vomiting induction) is an emergency intervention that should involve a professional on the phone while you act. You will see it sold as household 3% ONLY, and the label strength on the box is what matters for the math, not the brand. Reference data on this page reflects published veterinary sources, not a prescription for your dog.

What to have ready when you call the vet

Whether you are confirming a dose or reporting that your dog already got into something, the call goes faster with four facts ready: your dog's current weight, the exact product name and strength from the label, how much was given or eaten, and roughly when. With those, most clinics can answer in one call.

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.
