If you need to obtain Benadryl, it should be available at any drug store, pharmacy, or supermarket. Benadryl is sold over the counter, so you won’t need a prescription (for yourself or your dog. ) Make sure that you check the ingredients and purchase the version that ONLY contains diphenhydramine in it. Other formulations will include other ingredients that may harm your dog.
Make sure to consult with your veterinarian before calculating the dose your dog needs. You’ll likely need to break Benadryl tablets apart and estimate how many milligrams are in each.
All of the doses should be the same size. Do not give your dog different level dosages of Benadryl throughout the day.
Do not use Benadryl for this purpose on a daily basis. If your dog frequently seems anxious or uncomfortable, take the dog to your vet and explain the recurring symptoms.
Itchiness or hives. Swelling or inflammation from allergies. Runny nose and eyes. Allergy induced coughing or sneezing.
Veterinarians will have stronger medications at their disposal, and will be able to effectively treat a dog’s severe allergy symptoms.
For example, some Benadryl products will contain the drug acrivastine as their active ingredient. This drug is not safe for dogs to ingest, and should not be administered.
Also do not give your dog Benadryl if it has glaucoma, hyperthyroidism, or an enlarged prostate.
