Signs or Symptoms My Horse has Worms
First, we must discuss the difference between signs and symptoms because the 2 terms are often used interchangeably.
Signs: involves objective findings – things we can actually see for example, nasal discharge and weight loss.
Symptoms: involves subjective findings – is how one feels, based mostly on opinions.
For this section we will consider indicators of worm infection as signs, since horses cannot tell us how they feel.
There are four main types of internal parasites that pass through the horse’s body during their life cycle. Some may cause extensive damage and in the section below, we have listed them with the signs that the horse may show. We have also included bots, which primarily occurs in the horse’s coat and hair.
The best way to help you control worms in your horses so you will not see any of these signs is to have Horsemen’s Laboratory do periodic fecal egg counts to evaluate your Horses’ worm control program.
Horsemen’s Laboratory will also consult with you to discuss worm control practices and deworming medication if you desire. This consultation takes place over the phone so the many factors effecting worms in your horses can be thoroughly discussed.
