How to Give Benadryl (diphenhydramine) to Your Dog

You may want to know how to give Benadryl (diphenhydramine) to your dog if he or she suffers from:

  • Seasonal allergy symptoms
  • Skin allergy symptoms
  • Anxiety while traveling
  • Itchy insect bites
  • Reactions to poison oak or poison ivy
  • Other itchy, allergy like situations

Benadryl (diphenhydramine) is an over-the-counter pharmaceutical often used to treat dog allergies.

Diphenhydramine is the generic name for the name brand product Benadryl.

Before giving Benadryl (diphenhydramine) to your dog, always double check the package label and make sure the only active ingredient in the product is diphenhydramine.

Benadryl (diphenhydramine) relieves dog allergy symptoms such as runny noses and watery eyes.

Benadryl (diphenhydramine) can also be used to reduce anxiety and motion sickness when traveling.

Drowsiness is a common side effect of Benadryl (diphenhydramine).

The standard recommended Benadryl (diphenhydramine) dosage for dogs is 1 mg/lb every 8 to 12 hours, given two to three times daily.

We recommend starting at 1/2 the standard dose, to see if the lower dose works to alleviate the symptoms. If symptoms are no alleviated in 30-40 minutes, add the difference to obtain the full dose.

A single dose can be doubled to 2mg/lb if needed.

Double-dosing is usually done in emergency situations, such as your dog suffering a snake bite or digging up a wasp nest.

The standard dose in a Benadryl (diphenhydramine) tablet is 25 mg.

If you have a small dog, you may need to purchase children’s or infant Benadryl to obtain the correct dose. Remember, always look a the label!

Benadryl (diphenhydramine)usually takes approximately 30 minutes to start working.

If you’re using it to treat anxiety in dogs or to prevent motion sickness administer the medicine 30 minutes before the stressful event or journey is expected.

Note: You shouldn’t give any medication to your dog without first checking with your vet! Dosages can differ depending on our dog’s breed, medical history, and other factors.
