Can I Give My 20 Lb Dog Tylonal For Pain. Unfortunately tylenol, aspirin and ibuprofen are all not recommended for dogs. The prescribed dosage depends on your dog’s weight.

However, without knowing your dog’s current health status and any other medicines they are on, it is not safe to give. Tylenol is easily toxic to dogs due to a small margin of safety. No, you must not give a dog tylenol for pain.
