Is Benadryl Safe for Dogs?
Benadryl (diphenhydramine) is safe for dogs when given at the appropriate dosage. It is an antihistamine that can help alleviate symptoms of allergies, such as itching, swelling, and sneezing.
The medication comes in various forms, including tablets, capsules, and liquid, and the dosage will vary based on your dog's weight, age, and overall health status.
However, dogs with certain medical conditions may not be good candidates for Benadryl and should only be given the medicine under the guidance of a veterinarian.
Consulting with a veterinarian will help ensure that you use Benadryl safely and effectively to manage your dog's symptoms.
How Much Benadryl is Recommended for Dogs?
When administering Benadryl to dogs, the general recommendation is to give 2 to 4 milligrams per kilogram of body weight, or 0.9 to 1.8 milligrams per pound of your dog's body weight 1-2 times per day. The effects of the medication typically last for around 6-8 hours.
Liquid Benadryl is typically recommended for dogs weighing less than 10 pounds, as this can make it easier to achieve an accurate and appropriate dose.
For dogs weighing more than 10 pounds, most veterinarians recommend tablets, which come in 25-50 mg sizes. Achieving the appropriate dose requires breaking the tablets into quarters as closely as possible. However, it is important to note that the exact dosing will depend on your dog's individual needs and medical history.

Tablets or Liquid?
Liquid is ideal for cats and dogs weighing less than 10 lbs, and tablets are preferred for pets weighing more than 10 lbs. Make sure to check the ingredients of liquid Benadryl for the artificial sweetener xylitol, as it is toxic for dogs. For those pets who do not like the liquid flavors, the tablets can be more easily hidden in tasty treats.
The typical recommended frequency of Benadryl for pets is up to 3 times per day (every 8 hours in a 24-hour period). Always consult with your veterinarian to find out how often your pet can safely take Benadryl and never give more than the recommended dosage of Benadryl or more often than every eight hours in a 24-hour period. Giving more than the recommended dose of Benadryl or giving too many doses in a 24-hour period increases the risk of Benadryl overdose in your dog or cat.
If you’d like to chat with a veterinarian about a safe dosage and frequency to administer Benadryl to your pet, a virtual vet visit is a great way to connect with a doctor quickly without leaving home.
Liquid Benadryl Dosage Formula for Dogs
If you need to calculate the appropriate liquid dosage of Benadryl for your dog, you can use a simple formula. First, divide your dog's weight in pounds by 2.5. The result will give you the appropriate dose in milliliters (ml).
For example, if your dog weighs 10 pounds, you would calculate its dosage as follows: 10lbs ÷ 2.5 = 4 ml.
Once you have determined the appropriate dosage, you can measure it using a syringe or a measuring spoon. It is important to note that one teaspoon is equal to 5 ml, so if your dog requires a dose of more than one teaspoon, you will need to use multiple teaspoons to measure the appropriate amount.
