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.
