There are several variables to be considered when planning a deworming program for your horse. The age of the animal and environmental conditions play a key role. Younger animals, foals to 3 year olds, require more frequent deworming than adults. Horses on large pastures require less frequent deworming than stable/turn-out horses. Please come in to discuss your horse’s specific conditions with one of our veterinarians and we will be happy to customize a deworming program for you.
