[This review was collected as part of a promotion.] Frontline is perfect protection from fleas and ticks for your furry loved ones. We use these monthly to maintain our dog from those pesky fleas and ticks. I would highly recommend this product. Don't let fleas overtake your animals that can then infect your home. Great product and so worth the investment for your pets.
