Gelatin capsules are commonly used to encapsulate foul-tasting medications to make oral administration of these drugs more convenient. Size #5 is the smallest capsule. Size #00 is the largest capsule we stock. Typically, #3 and #4 capsules are used to pill cats and small dogs. #5 capsules are typically used with kittens, puppies, rodents, and birds. Larger capsules such as #1, #0, and #00 are used to pill larger dogs.
