This stuff works great kills fleas within 30 minutes to an hour, but it will not protect against reinfestation. Pet needs to be treated to control reinfestation and house and yard needs to be treated also.

This is the first time I've tried this product with my dogs, so far I have not seen them scratching or making any noise since I have given them these pills. I did see a flea jump off of one of my dogs. I will continue to use when necessary and I would recommend it. It's expensive, but it's worth it.
