Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

Puts my mind at east

We live in the country so we have trees and tall grass all around us. I have looked into other products for tick and flea control, but I was drawn to this one because it not only kills fleas at all stages of life, it actively repels both ticks and fleas. I believe the claim because she has never had fleas and we have only ever seen one tick on her and it was dead. I will continue to use this product and don't see myself changing.

I ordered flea and tick for my Yorkies and I was very surprised and happy it took three days from the order to getting it. I thought I have to wait 7 to 10 days but it was there within two days and I was very happy about that because I was already a week behind in their medicine, so they are great

They were always great

I bought them gir my sweet Cherie. However, she said, “Mom, it’s time I cross the rainbow bridge.” We hood her as she slipped away and Cherie is in my heart until we meet again. I miss her so much, she was my unconditional love for 17-1/2 years thanks to a lot of love and meds from Chewy. So I gave them yo her vet for some unfortunate dog. But my husband, Phil, bought a maltise pup so we will be ordering flea, tick snd heart worm meds for her.

I had to give my poor pup another dose after 3 weeks to give it a chance to work but still no relief. Going to try Simparica next

Appears to do the job

Have used it for several years now on two dogs. haven't seen them scratching. One dog has an initial sensitivity to the product that causes some scratching for about a day after application then he's okay.

Vet recommended

My chihuahua has skin allergies and the dog dermatologist recommended this flea/tick prevention. It works, and doesn't aggravate my dog's skin. As usual, Chewy has great prices and great service!
