My dog has allergies this time of year, March. The meds from the vet work ok (25 mg. of Hydroxizone) but my sister gives her dog Benadryl for his allergies & it works much better. My dog coughs, sneezes, etc. He is a black Lab/ Great Dane mix & weighs about 89-95 lbs. How much Benadryl would he get, 1 or 2 tablets?
You have to talk to your vet about this. vetcare
