Review title: Fleas have developed a tolerance
Product review: It appears that the fleas have developed a tolerance for this product in our area. After a week or two I have spotted fleas and my puppy is still itching and pulling out his hair. It did appear to work for ticks which is why I opted for this brand over an oral flea control but I may have to alternate since the fleas don't seem to be affected. :(
