Heartworm Preventatives
There are several types of heartworm preventatives available.
At the Howell Veterinary Care Center we keep in stock the safest and most effective heartworm preventative.

Examples are:
  • Heartgard, a meaty chewable chunk given once a month throughout the year. This medication prevents heartworms, hookworms and roundworms.
  • Sentinel, a chewable tablet given once a month throughout the year. This medication prevents heartworms, hookworms, roundworms,whipworms and flea infestation.
  • Tri-Heart, a chewable tablet given once a month throughout the year. This medication prevents heartworms, hookworms and roundworms.

There are other products available that can be ordered if requested.

  • Cats can be infected with heartworm disease and we may recommend placing them on monthly preventative when indicated.
