When selecting a paste dewormer, knowing the type and number of parasites in your horse is imperative. Ask your veterinarian to perform a “fecal egg per gram” test at least once per year, or order our Equine Worm Test Kit. Experts recommend administering a paste dewormer for worms like small strongyles at the beginning of the grazing season in your area and as needed throughout the year according to fecal test results. It is also important to use a paste dewormer that controls bots and tapeworms once or twice per year. Be sure to dose your horse according to his weight. If you’re not sure how much he weighs, order our handy Weight Tape or use our Equine Weight Calculator. Most importantly, work with your veterinarian to develop a strategic program that is appropriate for your horse, depending on factors like climate, travel and living conditions.
