This product did not remove fleas from any animals. It caused hair loss and chemical burns where applied. I bought enough and treated every single animal in the household, treated the yard and the furniture, yet months later (while continuing application) the fleas remained rampant! Buy NexGuard instead. Chewy should remove this product.

I have a large Labrador Retriever/Beagle mix but he physically is ALL Lab. He's a big boy but he's all muscle. I was thoroughly impressed with how well this Nextstar Flea & Tick Topical for large dogs (89-132lbs) worked on my pup! I haven't seen any fleas, ticks, scabs or any other signs. My dog isn't constantly scratching like he was. I definitely prefer to use a topical serum over an oral medication. It stayed well on my dog and offered full protection. Great product that I highly recommend to all dog owners of all sizes and breeds.

I got this product from a site to try samples and write a review. I got a call to ask if I would foster a dog a few days after receiving the sample. I was told only thing is he had fleas really bad. I would not bring him in with my animals until the fleas was taken care of. I decided to try this product on him and it worked great, you could see the fleas dropping off of him. I gave him a bath and he was flea free in no time. I would highly recommend this product. Easy to use and works great.

Not a very good product

This did not help with fleas at all. As a matter a fact it seems like it got worse.
