Review title: This particular order is not good
Product review: I have always used Frontline Plus on my dogs (for years) to control fleas and ticks and it has worked so well. The last order i received a month ago does not work at all. I don't know if something is wrong with the batch or they've changed the formula but it doesn't compare to what I've bought in the past. I am very disappointed because Frontline has been such a good product for so long.
