About This Item

Details

  • Parasite Protection: Selarid is an FDA approved, once-a-month topical application that kills adult fleas, prevents flea eggs from hatching for one month, and prevents deadly heartworm disease in dogs.
  • Multi-Pest Treatment and Control: Beyond fleas and heartworm, Selarid treats and controls ear mites and sarcoptic mange, and controls tick infestations due to the American Dog Tick.
  • Easy to Use: The convenient topical application is applied to the skin at the base of the neck, in front of the shoulder blades, making monthly treatment simple for pet owners.
  • Cost-Effective: Containing the same active ingredient (selamectin) as the pioneer, Selarid offers the same efficacy at a more affordable price point.
