What is Parastar for Dogs?

Parastar for Dogs is a one spot, topical flea, tick, mite and chewing lice treatment developed for dogs. The waterproof, topical solution kills adult fleas before they lay eggs, disease-spreading ticks, and chewing lice, and prevents pest infestations. It also controls mites that may cause sarcoptic mange. The easy to use applicator is applied to a single spot and provides flea and tick protection for one full month. Parastar for Dogs is gentle enough for use on puppies eight weeks of age or older.


Dogs (8+ weeks of age)


  • Kills fleas, ticks and chewing lice for up to 30 days
  • Controls mites that may cause Sarcoptic mange
  • Fast-acting, waterproof, topical solution
  • Easy to use single spot application
  • Approved for dogs and puppies 8 weeks of age and older

How does Parastar for Dogs work?

Parastar for Dogs contains fipronil, an insecticide that targets the nervous system of pests. The topical treatment is applied to the skin and spreads into the hair follicle, killing adult fleas before they lay eggs, ticks (brown dog ticks, deer ticks, American dog ticks, lone star ticks) that may transmit Lyme disease and Rocky Mountain spotted fever, and chewing lice. In addition, it also controls mites that may cause sarcoptic mange.


Keep out of reach of children and pets.

Brand Name:

Parastar™ (fipronil)

What is the most important thing I should know about Parastar for Dogs?

What should I discuss with my veterinarian before giving Parastar for Dogs to my pet?

Tell your veterinarian if your pet is currently being given any other medications.

How should Parastar for Dogs be applied?

Weigh your dog to be sure you are applying the correct dose for the weight of your dog. The topical solution should be applied monthly to a single spot between a dog's shoulder blades. Monthly application is recommended for control of flea, tick and chewing lice infestations. Only one applicator per treatment is needed. Repeat application may be made if necessary, but do not apply more often than once every 30 days.

What are the potential side effects of Parastar for Dogs?

Sensitivities may rarely occur after using any pesticide product. Dogs may experience some temporary irritation at the site of product application. If signs persist, or become more severe within a few days of application, consult a veterinarian immediately. If your dog has an unusual reaction to the initial application, consult a veterinarian before repeating treatment.

What happens if I miss giving a dose of Parastar for Dogs?

Apply the missed dose as soon as you remember and then resume the monthly application schedule thereafter.

What happens if I overdose my pet on Parastar for Dogs?

If you suspect your pet has ingested Parastar for Dogs, consult your veterinarian or emergency veterinary clinic immediately.

What should I avoid while applying Parastar for Dogs to my pet?

For external use only. For use on dogs and puppies only. Do not use on puppies less than eight (8) weeks of age. Avoid contact with eyes, skin or clothing.

Parastar for Dogs is rated 3.1 out of 5 by 11.
Rated 4 out of 5 by from great product but he wont eat it! He used to gobble down the HeartGard product. my vet assures me Parastar is a better protection for my dear Teddy...but I need to grind it in the food processor with chicken to have him eat it. and the pellet does not crush down entirely (even in the food processor) so he spits those out! please make it softer and make it taste better so the dog can reap the benefits.

Rated 1 out of 5 by from A bad batch? I've used Parastar in the past with good results, but the last dosage that I purchased has been non effective against fleas; I'm wondering if maybe it was a bad batch or something....I will have to switch to something because I cannot allow my home to become overrun with fleas.

Rated 5 out of 5 by from Very effective. Kills ticks!! This product works! Our dog has never had fleas and we live in a high tick area and Parastar has paralyzed and killed any ticks that get on our dog. I just saw a dead on the other day, with no signs of engorgement. Since starting to use Parastar with our dog 3 years ago, we haven't had any ticks or fleas! And our dog tolerates it well, unlike Vectra, which my vet prefers. Just remember, you do need to apply this every month, you can't expect results if you're not using it properly.

Rated 5 out of 5 by from This is AWESOME! We have 2 German Shepherds and we have given them both Parastar as soon as they were old enough. Even in rural Arkansas where ticks and fleas abound, our dogs stay tick free. We used to get Parastar from our vet, who has since stopped carrying it, and when they sold us the last box they had, I panicked! Nothing has helped our dogs as much as Parastar. They don't even have to wear a flea collar anymore, even at the peak of tick season. Thanks 1-800-Petmeds for saving our dogs from flea-saster!

Rated 5 out of 5 by from Awesome product! I walk my two dogs in the woods and fields by our home twice a day every day. Parastar is absolutely the best flea and tick prevention product I have ever used! I have never seen a flea on either dog and the rare tick that I find is already dead.

Rated 1 out of 5 by from Waste of Time & Money! Our vet recommended this product as a new & better alternative to Advantage because it had Tick preventative also. We had just moved to a new home with woods behind it and we'd already seen a few ticks, so we jumped on the vet's recommendation. What a waste of time, money & effort! It would have been more effective to just rinse the fleas off of them with some water...Parastar is USELESS! Used this stuff for 3 mos because they said sometimes it takes more than one application to see full effectiveness. Ha! 3 mos. later and the dogs & cat went from a few fleas to completely infested with fleas & it didn't deter a tick one. Had to wait a month after last application to be able to switch back to advantage (& used Capstar tabs) to help alleviate some of the fleas from the pets quickly. Within a week, we were flea free on Advantage. We have tried to deal with the ticks by yard sprays & Diatomaceous earth application instead (safer/natural alternative) and have had good results there. STAY AWAY FROM THIS PARASTAR if you actually want flea & tick relief/protection for your pets.

Rated 5 out of 5 by from Never seen a flea or tick We have always looked at this as preventive, not curative. Can't say how it would work where there was already an infestation, but being right next to a park and woods with multiple animals coming through the yard and with many playmates in the neighborhood, we have never even seen a flea or tick.

Rated 1 out of 5 by from Don't use! The vet applied this to my 2 dogs and it didn't make a difference, after flea dips and mutable baths from myself there are still fleas! Don't use this product!!

Since your furry baby is under the recommended weight range, you may want to consult with your veterinarian to see if this product is safe to give to your furry baby.

What is the amount of product in the tube of parastar? I didn't see that anywhere on the page.

Depending on the size tube you purchased: the 4-22lbs.size conatins (0.023 fluid ounces) the 23-44lb. size contains(0.045 fluid ounces), 45-88lb. size contains(0.091 fluid ounces) and the 89-132lb. size contains(0.136 ounces). Which converts to the 4-22lb.size = approx.0.69 ml's, the 23-44lb.size= 1.35ml's, the 45-88lb. size= 2.73ml's,and the 89-132lb. size=4.08ml's. Thanks for your question.
