Oh that is such a sad story. We were debating to wait it out and see what happened, but the vet said that you won't know until the dog starts bleeding and by then it's probably too late. That, and with a small dog they don't stand much of a chance. She said he probably didn't eat any, but we were happy to get him checked out and on meds just in case. I hate poisons for so many reasons and this is just one of them.
Thank you so much!
