Review title: This stuff doesn't work!
Product review: I have been using Frontline Plus monthly, from March through August, 2012, and have documented the doses to be positive I gave it as noted. Last week, a friend took my standard poodle in for several days while I was out of town. The first evening, she called to say the dog was going to the kennel, as he was covered with fleas! When I discussed with my vet, he said the manufacturer was investigating for lack of effectiveness.... that there may be an immunity that has developed in the flea population.Be careful....
