Our take on the NEXTSTAR Flea & Tick Topical Prevention for Dogs 23-44 lbs, 3-Month Supply

NextStar is a monthly topical flea and tick treatment for medium and large adult dogs in the 23-44 lb range. It pairs fipronil, which kills adult fleas and ticks, with (S)-methoprene, which stops flea eggs and larvae from developing, so it breaks the flea life cycle rather than just killing what is on the dog. The formula is waterproof and the box covers three months. It is the same active pair used in Frontline Plus, so it competes on that proven combination rather than on a new ingredient; buyers who want an oral chew or a repellent that also blocks mosquitoes should look elsewhere.

Best forMedium and large adult dogs, 23-44 lbsOwners who prefer a topical over an oral chewHouseholds fighting fleas that keep coming backDogs that swim or get bathed often
Pros
  • Fipronil plus (S)-methoprene kills adults and stops eggs and larvae
  • Waterproof once dry, so swimming and baths do not strip it
  • Three monthly doses in one box
  • Same active ingredients as the widely used Frontline Plus
  • Splits the flea life cycle, which helps break infestations
Cons
  • No mosquito or tick repellency beyond what fipronil provides
  • Not for puppies under 12 weeks
  • Weight bands are narrow, so a dog near a boundary needs the right size
  • Some dogs show skin irritation at the application site
  • Topicals leave a greasy spot until dry

Questions and answers

How does NextStar compare with Frontline Plus?
It uses the same two actives, fipronil and (S)-methoprene, in a waterproof topical. Expect similar flea and tick performance; the difference is brand and packaging, not the chemistry.
How often do I apply it?
Once a month, for three months with this box. Each dose is labeled to last about 30 days.
Can I bathe my dog after applying it?
Yes, once the solution has dried at the application site. The formula is waterproof after that, though frequent shampooing still wears it down faster.
Is it safe for puppies?
Only for puppies over 12 weeks old. Younger puppies and pregnant or nursing dogs should be cleared by a vet first.
What if my dog is near the weight limits?
Use the band your dog falls in. A dog just over 44 lbs needs the next size up, and a dog under 23 lbs needs the smaller size.
Does it kill ticks and mosquitoes too?
It targets fleas and ticks, including flea eggs and larvae. It is not a mosquito repellent, so do not rely on it for mosquito-borne disease prevention.
Where is the NEXTSTAR Flea & Tick Topical Prevention for Dogs 23-44 lbs, 3-Month Supply cheapest?
At Walmart, for $34.99, as of our latest check.
Where can I buy the NEXTSTAR Flea & Tick Topical Prevention for Dogs 23-44 lbs, 3-Month Supply?
