Is Parastar Plus for Dogs right for your dog? Yes! Dogs who take daily walks or love trips to the dog park are at greatest risk. But, so are those who share a home with outdoor pets or frequently visit groomers or boarding kennels.

Fleas and ticks pose a year-round threat. Not only can these pests cause skin irritations that can make life miserable for your dog, they may also transmit diseases to both your dog and your family.1,2

Parastar Plus for Dogs is approved for use on dogs and puppies 12 weeks of age or older and 4 pounds of body weight or greater.

A dangerous duo: ticks and fleas

Ticks All ticks are a nuisance, but some are downright dangerous. Parastar® Plus for Dogs provides broad-spectrum tick protection for your dog’s adventures.

  • Ticks carry bacteria that can cause diseases such as Lyme disease and Rocky Mountain spotted fever.2
  • All tick-borne diseases start with a bite. The time it takes for ticks to transmit disease is variable, but can occur in as little as 3 hours.2 The likelihood of disease transmission increases the longer the tick is attached.
  • Even when the temperature drops below the freezing point, ticks are still around. Some species come equipped with tick antifreeze to help them survive during the winter.3


  • Fleas may cause your dog to be extremely uncomfortable causing them to scratch, chew, bite, incur fur loss or experience restlessness.
  • Fleas are the source of flea allergy dermatitis (FAD), a common veterinary skin condition in which secondary infections can also develop.
  • Severe infestations may cause anemia, iron deficiency and in small dogs, even death.
