[This review was collected as part of a promotion.] I have been using this on my dogs for years, no side effects and good protection.

It worked at first. Later, my dogs became immune to it. Fleas all jver them. Had to spend lots of money to get rid of them. One dog got sick.

The shipping was fast, only problem this was to be new unopened. The outside of the carton was opened, the viles seemed ok.

I've used Frontline on my dogs for decades...many different dogs over the years. This product has worked great.

Works well for my extremely large country dog. He enjoys water play in the pond and frontline stays working.

Frontline Plus does not work for our dogs anymore! They still had so many fleas after a few months of use!

I have 9 dogs I applied this Frontline to all my dogs and this stuff did not work this time, Usually it does but this time no,so I want a Refund

Walmart is the only place that I have found to order larger quantities of this product at a decent price.
