Reviews for Frontline Top Spot for Dogs 45-88 lbs, Purple, 12 Pack (1013916)
Have been using this for over 6 yrs with our dog. We have a wooded yard and she plays with other dogs too. So far in 6 yrs - no incident of any fleas or ticks. My daughter once had a tick on her leg after a walk in the woods but none on the dog :) So overall I am very happy with this product.
Works like a charm!
Frontline is #1. It's the real deal.
