My chihuahua ate 1/2 block of rat poison about 5hours ago. What should I do?
Welcome! My name isXXXXX am a UC Davis graduate, and currently, a Medical Director of a veterinary hospital.

I am sorry to hear about this concern.
Rat poison.
If you have the box it came in or anything on the bait, I need to know the name of the active ingredient.
For example, Bromethalin

Hello Dr, Andy


It contains difethialone, an anticoaghulant



No, it is too late to induce vomiting. Ideally, vomiting should be induced no later than 1 hour after ingestion, and much better within 15 to 30 minutes.

Absolutely, get into a vet right now! No delay
This anticoagulant works by causing uncontrolled bleeding. It is a vitamin K antagonist, meaning, that getting extra vitamin K may block its effects.

You want to get to a vet right now who will likely give a vitamin K shot and follow it up with a few weeks worth of vitamin K supplementation.

Don't take a wait and see approach. Bleeding can start up to 3 days later, and once it starts, it is more difficult to treat.

Sorry to hear about the intoxication.
Starting vitmain K now can be life saving therapy.

Please let me know if there is anything I did not cover for you. I hope that information has been helpful.

Can I buy vitamin K anywhere and give it to them at home?


Hi Thelma, I would not. You need accuracy and 100% confidence you are giving the right product, and that injection to start working now can be very important. Remember, 5 hours has already past, it was 1/2 a block and you have a small breed dog. Meaning, it may have a greater impact. I would get into the vet for 100% certainty on what to get, how much of it, and probably the injection. Many vets will also encourage checking a clotting blood test now as a baseline and rechecking it in 3 days to see if any changes are occurring.
