Q. What happens if my dog eats a rat that has died from ingesting antifreeze? Will he ethylene glycol kill the dog too, or is it digested enough by then?

Answered By

A. I have to say I have never been presented with this question, nor do I see anything like it in any of my veterinary resources. Dogs eat rats that have been exposed to rat poison all the time, and that's not usually enough to cause harm in the dog. However, because I cannot tell you with any certainty about how a rat's body metabolizes antifreeze and whether it is toxic by secondary ingestion, I would most certainly take your dog in for blood work today and an exam to make sure that he is OK.
