I suspect that my dog has possible poisoning from flea/ tick medication that I applied to his coat a day and a half ago. I applied the treatment on Wednesday night and yesterday his demeanor completely changed. He's had reoccurring diarrhea, vomiting, weakness, lethargy, loss of appetite, and a little bit of reddish, bloody, jellied stool. What procedure will a vet use with him? Can a vet prescribe antibiotics and pain meds to clear it up? Money is an issue for me, so I am financially struggli

I am sorry to hear that Peanut is feeling so cruddy To be honest, that kind of reaction from flea / tick medication starting 24-36 hours after application would not be very typical. Usually signs of illness would start pretty shortly after. The only reason it could be delayed is it Peanut waited awhile and then managed to lick the stuff off his fur. Depending on the type of drug that was used, some have antidotes while others are just treated supportively. There are no antibiotics that are used to help with this kind of issue, unless the vet believes that one might assist with inflammation or prevent a secondary infection. Based on the clinical signs you have described, the best medication that the vet could prescribe would be something to nausea, diarrhea, and acid production. In terms of diagnostics I would run if you came into my office with these symptoms, I would definitely recommend starting with some baseline blood work and potentially some x-rays to rule out a possible foreign body in the intestines. Hope this is helpful.
