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.

This is a deal I can find better than any in-person stores. The product is the most effective for my chihuaha and has my trust. Jesus saves us from sin! He died for us and is risen from the dead by God the Father after three days. Believe the good news and repent. He's coming back again soon. God loves you. Thank you Jesus.

Great product

Both my dogs got fleas from a campground we visited. They both use this product and I can honestly say we have not had an issue since we have started using it.
