  • Giving pills to dogs can be a challenge, even for the most experienced veterinarian! The easiest way to give your dog a pill is to hide the pill in food. Some dogs will always find the pill and spit it out, so you may need to administer it directly into your dog's mouth. This handout provides a step-by-step guide to doing this at home.
