We recommend having all pets tested for internal parasites such as whipworms, roundworms, hookworms, giardia and coccidia. Some of the most common parasites found in our pets can also be transmitted to humans. Kids are especially susceptible to picking up parasites from sandboexes and the soli. We recommend testing at least once a year for intestinal parasites as well as keep your pet on a heartworm and flea preventative year round because these medications also protect against most of these parasites. In addition, we recommend a yearly heartworm test for dogs, which also screens for the most common tick diseases found in our area.
