All horses which graze in pastures ingest parasite eggs that are found throughout the environment. The actual parasite burden for any individual horse depends on its age, the number of horses on the same pasture, and the pasture’s size and quality. As a result, your veterinarian will recommend a fecal exam on each individual horse to determine the proper deworming program for each horse. Internal parasites of horses can cause many intestinal problems, including gastrointestinal upset, diarrhea, and potentially colic. Our knowledgeable veterinary staff will design a preventive medicine program for your horses based on their exposure to these diseases.
