What can I give my dog for a grass allergy? If symptoms and irritation still occur, and your dog is uncomfortable, be sure to call upon your local veterinary professional for help. They might be able to recommend anti-itch shampoos and sprays to relieve discomfort, and may even prescribe allergy shots in severe cases.
Can you give a dog Benadryl for grass allergies? Benadryl is a great medication for use in dogs with mild-to-moderate allergies. Seasonal allergies, food allergies, environmental allergies, and allergic reactions to snake and insect bites all respond to Benadryl in most cases.
Can I give my dog Benadryl every day? According to the Merck Veterinary Manual, the safe dosage is 2-4 milligrams of medication per kilogram of weight, or 0.9 to 1.8 milligrams per pound. This amount can be administered two to three times daily, depending on your dog’s symptoms.
