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. You need to check with Chewy's vet to see if it's safe to give him, and the vet can give you the dose.

    I suggest you trust your veterinarian who knows your dog and her medical history. Your vet can adjust dosages with this knowledge. We here can only give general recommendations which will be in the region of average treatment. If your veterinarian determines this dosage to be correct for YOUR dog then this is what he believes your dog needs. This, however cannot be used as a general guideline for other dogs he or any other vet has not seen in person. So, no, you do not have to be worried.

    Unfortunately, it is illegal for the experts at Petco Pet Education Center, formerly Petcoach to prescribe a medication, even an OTC drug, without seeing the animal in person first. I would give your vet a call, and they can advise you if it's safe to give Oliver a benadryl or not. They can also give you the correct dose for his weight.
