My dog bit a rat and is bleeding. Is she poisoned? Emergency vet?

Updated on September 23rd, 2025

Pet's info: Dog | Beagle | Female | spayed | 5 years and 1 month old | 30 lbs

My beagle cornered a rat in the yard, she had it in her mouth, it got away, when I got her inside she's bleeding from the mouth, I don't know if it's because she bit the rat or the rat bit her. I looked in her mouth and can't see a puncture. I'm scared she'll get sick or poisoned by this nasty thing, should I take her to an emergency vet?

Rat bites do have the potential to cause illness and fever. If you notice fresh blood from the mouth, even after rinsing the mouth with water, then chances are the rat bit Lilly somewhere inside the mouth that isn't readily visible. An ER visit is needed if the bleeding doesn't stop and is profuse, requiring cauterization.
However, a regular vet visit on tomorrow is needed, even if the bleeding stops for tonight, because if the rat did bite Lilly then a prophylactic treatment with antibiotics should be considered to prevent an infection from festering.

    If she hasn't ingested the rat she cannot get poisoned from it, as long as she is vaccinated you d not have to worry about her getting any serious infection from the rat. Keep an eye on the bleeding and make sure it has stopped.
