Pet's info: Dog | Labrador Retriever | Male | unneutered | 60 lbs
You My dog just ate 40 potassium pills at 40 Mg a piece. I gave him 4 tablespoons of hydrogen peroxide and he’s currently vomiting this up less than 30 minutes after pill consumption. Is this something to worry about or will the vomit followed by plenty of water be okay for him??

Hi there! Good job thinking quickly and inducing vomiting. I would still recommend Dexter be seen by a veterinarian, for 2 reasons: 1) potassium in large doses can potentially have effects on major organs. Your veterinarian will be able to do a through examination as well as preform blood work to check potassium levels as well as administer treatment if necessary. Sometimes IV fluids and/or other medications may be necessary, 2) hydrogen peroxide can be very hard on the stomach and intestinal lining, your veterinarian may recommend medications to protect the gastrointestinal tract. Also fluids would help Dexter feel better after all the vomiting and IV (in a vein) is the quickest way to replenish those electrolytes. If Dexter’s attitude has changed or he continues to vomit for more than a hour, or you aren’t seeing pills in the vomit he absolutely needs to be seen by a veterinarian as soon as possible. Hopefully this information was helpful and Dexter feels better soon!
