Unfortunately, by law it is illegal for the experts at Petco Pet Education Center, formerly Petcoach to give the dose information for any drug, including OTC drugs, without seeing the animal in person first. That's because doing so requires a veterinary client patient relationship which cannot be achieved via an internet forum. In addition, the experts cannot say for certain if a specific drug is safe for your dog. I would not give this to Waldo unless prescribed for him by your vet, and under their supervision. You can discuss with your vet if this is safe to give him, and they can give you the dose information.

Your vet can determine if it's safe and appropriate to give him for his symptoms, and can tell you the dose.
