Query: timely and great price

Seems to be working for my dog, much cheaper than if I bought it at the vet or a local pet store. My dog is a longer haired breed (kind of a spaniel mix, from the pound) and we are active, dog park, walking trails (not quite hiking, Mommy's not that fit lol) etc and she sleeps in my bed and so far, no fleas. I highly recommend this product.Apparently it doesn't work with ticks as much? We walk in forests but she's on-leash, on the trail and not in the brush so I can't say whether we've had tick encounters or not.
