Any from of Tylenol can lead to liver failure, kidney damage, and compromise a dog's oxygen respiration rate, according to Jennifer Coates, DVM for PetMD. Pet owners are strongly advised against giving their dogs any over-the-counter pain medications that are intended for human consumption.
Due to the potential risk of negative side effects, it is best to discuss a dog's pain management with a licensed veterinarian, notes Coates. There are several pain medications designed specially for pets that are much safer than human drugs. Additionally, some conditions may not require the use of pain medications and can be treated with healthy dietary supplements, such as omega-3 fatty acids for arthritic inflammation.
