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.

The orders I received was doubled. I wasn’t happy . There were things that were sent I couldn’t send it back. Some things were tripled. The orders together were $915.00. It was a total shock. Everyone Please Watch. So This Does Not Happen to You.

I tried Brevecto topical. Fleas were still biting and present on both my dogs for 2 weeks after application. I flea combed them after every time they went outside!!

Good stuff! Seems to work well.

But, I'm switching to a Sorresto collar because the Vectra comes off on our fingers & numbs my face!

Fleas are gone!! Strongly recommend.

We have a senior chihuahua with a history of seizures; strong flea medication is always a worry. We were recommended Vectra and it worked. Fleas were gone the next

We have a senior chihuahua with a history of seizures; strong flea medication is always a worry. We were recommended Vectra and it worked. Fleas were gone the next day no more scratching and no seizures. Vectra is also half the price of the other comparative companies will order again.

Flea and tick

Dogs are still biting not sure if it’s just not working or it did not seem like there was anything in the tubes. I treated 2 puppies and couldn’t see the product

Dogs are still biting not sure if it’s just not working or it did not seem like there was anything in the tubes. I treated 2 puppies and couldn’t see the product really on their skin or fur. My larger dog I could definitely see the product.
