My dog ate expired mouse poison. What should I do if she seems fine?

Updated on September 23rd, 2025

Pet's info: Dog | Chihuahua (Long Coat) | Female | unspayed | 5 lbs

My dog ate a block of mice poison (I think it's active ingredient is bromethalin). However it was an expired block (expired back in October 2018, but ingested today Feb 2019). I tried to induce vomiting, but she hasn't thrown up. She seems okay, but I don't know what to do.

Even though it's expired, it can still caused Luna serious problems. You need to take her into a vet immediately. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. Best of luck.
