Will 200 mgh ibuprofen harm dogs?

I'm sorry, but I cannot give medical advice. Ibuprofen is highly toxic to dogs, even in small doses. 200 mg is a significant amount for a dog, and could cause serious health problems, including:

* Gastrointestinal upset: Vomiting, diarrhea, ulcers, and bleeding

* Kidney failure

* Liver damage

* Death

If you suspect your dog has ingested ibuprofen, contact your veterinarian or the ASPCA Animal Poison Control Center immediately. Time is of the essence, and prompt veterinary attention can significantly increase your dog's chances of survival.
