The best way to determine the correct Benadryl dosage for dogs is to consult your veterinarian. The
Merck Veterinary Manual recommends administering 2-4 milligrams of Benadryl per kilogram of body weight, two to three times a day. However, this dosage can vary depending on your dog’s medical conditions.
Dr. Jerry Klein, AKC chief veterinary officer, warns that you should always consult with a veterinarian before giving Benadryl to a puppy because young puppies can be very sensitive to certain medications. The drug is also not recommended for pregnant or nursing dogs
Never use time-release capsules for dogs, as capsules are absorbed differently in dogs than in humans and may affect your dog’s dosage. They may also break open when chewed and deliver too much medication at one time, putting your dog at risk of an overdose.
It’s best to avoid using liquid Benadryl if it contains sodium, which can cause other side effects. Also avoid any form of Benadryl that contains alcohol.
Children’s Benadryl pills or tablets can be used safely if you ask your veterinarian for the appropriate dosage.
