Review title: Frontline Plus has Changed ?
Product review: 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.
