Merial Frontline Plus Flea and Tick Control for 0-to-22-Pound Dogs and Puppies, 6 Doses

I have used this for years without a problem, but I believe that they have changed the formula, because it quit working a few months ago when I bought my new batch. My vet said that they have gotten a lot of similar complaints, and that long time users have switched to other products. I am now using Advantix which works great, and also is supposed to repel mosquitoes, but there have been some cases where Advantix causes a skin reaction in some dogs, so you might want to try a single dose before buying an entire package.

I wonder if these mail order purchases are old stock from before a possible formula change.

Frontline Plus has always kept my dogs flea and tick free. In addition, it is odorless and less oily than other products I have tried. I have never found a better price for it than at Amazon.com.

- Product arrived as described.
- Arrived within the stated shipment time frame. Well packed too.
- Item that arrived WAS NOT expired either (this was something my vet warned me about regarding online purchases).
- I highly recommend this product to others looking for a good flea and tick removal for dogs. It must be used monthly as the instructions state. It has always done what it has stated to do and I do take my dog hiking in the woods near when I live and not once has he had a flea or tick.

The product works great! We put it on our chihuahua and shih tzu and the fleas disappear. I was skeptical at first, but Frontline proves me wrong.

The product works well although my dog begins to endlessly scratch herself for days after the application.
