It is frequently prescribed by veterinarians for allergic reactions, insect stings and even anxiety during travel. However, while it is generally safe, always consult your vet before using Benadryl on your dog to make sure it is the right treatment.

Benadryl Dog Dosage: How Much Is Appropriate?

The general guideline for Benadryl dosage for dogs is 1 mg of Benadryl per pound of body weight. This dosage can be given two to three times a day, depending on the severity of the condition and your dog’s tolerance.
