Heres what you need to know about how much Benadryl your dog should take and when you need to see the vet.

Benadryl dosage for dogs.

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.

How do I calculate liquid Benadryl dose for dogs?

To calculate the liquid Benadryl (12.5 mg/5 ml) dose:

  • Determine the dose you need. The standard Benadryl dose is 1 mg per 1 lb.
  • The standard dose is the weight of your dog in pounds (lb).
  • Let’s count how much Benadryl is in one milliliter of a drug. 12.5 mg/5ml = 2.5 mg/1 ml.
  • Now we have to divide the desired dose by the amount in 1 ml.
  • The dogs weight in lb/ 2.5 mg = the amount of liquid Benadryl you want to give to your dog.

  • Allergies: Benadryl is a brand name for a type of drug known as Diphenhydramine – an antihistamine used to relieve symptoms of allergies, such as rashes, itching, and dog eye allergies that can come from seasonal or environmental allergens.
  • Anxiety: Benadryl contains soothing properties, which can promote calmness in dogs during high-stress situations (i.e., fireworks, thunderstorms).
  • Insomnia: For dogs with trouble sleeping, Benadryl can make your dog feel drowsy and promote sleep.
  • Itching: Diphenhydramine can decrease itching and minimize the reaction of insect bites and bee stings.
  • Motion sickness: Since the active ingredient in Diphenhydramine is similar to the active ingredient found in Dramamine (a motion sickness drug), Benadryl can be useful to treat nausea and motion sickness when traveling.

    • While Benadryl is FDA approved for human use, it is not FDA approved for animal use, though some types of Benadryl are considered relatively safe for dogs and cats.

    Can Benadryl Be Used for Dog Allergies?

    Benadryl is an antihistamine that blocks the H-1 receptors on smooth muscle and blood vessels. Taken orally, Benadryl can be mild to moderately effective for dogs experiencing mild allergic symptoms.

    Vets commonly use it to treat environmental allergies and allergic reactions to insect bites or stings. It can also be used as a pre-treatment for possible vaccine reactions.

    But if your pet is having an acute allergic reaction with facial swelling or difficulty breathing, take them straight to the vet. Many allergic diseases also require a combination of allergy medicine and treatment of underlying infections.
