Deworming schedules may vary depending on several factors such as the age and lifestyle of your pet. Puppies and kittens typically require more frequent deworming than adult dogs and cats. If your pet is exposed to high-risk areas where worms thrive, it is recommended to deworm your pets every 3-6 months. If they are on a regular flea/tick preventative, several of them contain a dewormer as well. It is best to follow your veterinarian's recommendations for deworming intervals and products.
