Heartworm Testing and Prevention

DVPH follows the recommendations of the National Heartworm Symposium.

  • For our geographic region, we recommend all puppies begin monthly heartworm medicine by 16 weeks of age. 
  • Heartworm medications need to be given year round.
  • As added protection, heartworm testing (a simple blood test) is advised annually, even with year-round prevention, at the time of routine vaccinations.                            

Flea and Tick Prevention

     It only takes one warm day to bring about fleas and ticks, thus DPVH advises giving year-round preventive care. Recommended products include:

  • Nexgard for puppies until six months of age.
  • Bravecto for mature dogs, given every 12 weeks.
  • Revolution for cats and kittens, given monthly.
