A number of common medications, including ibuprofen, are highly toxic to dogs. In fact, ibuprofen can even be fatal in some cases. If you suspect Rover has ingested even over-the-counter meds such as ibuprofen, get him to the vet -- rush if you notice symptoms of poisoning.
The most common -- and milder -- side effects of ibuprofen include diarrhea, vomiting and abdominal discomfort or pain.
More Serious Problems
One of the major risks of ibuprofen consumption in dogs is renal failure. This usually happens at large doses of about 175mg per kilogram of body weight. However, DMV360.com points out that very young or senior dogs -- as well as those who are sick or have compromised immune systems -- might experience kidney problems at much lower doses. Seizures, coma and death are also a possibility.
