    Thanks for your feedback!

    Highly recommended!!

    Posted by iHerb Customer on May 01, 2017 | Verified Purchase

    I have 3 dogs. I live in Texas. In the Spring & Summer (sometimes Fall!), the fleas appear! This flea control has the same active ingredient as Frontline. I've priced it many, many places, online as well as brick & mortar, iHerb has the best price hands down! With 3 dogs, quality as well as price matters! You can't go wrong w/this product! I highly recommend!!

    Thanks for your feedback!

    Just put first dose on dog not long enough time to really evaluate

    Posted by iHerb Customer on May 03, 2016 | Verified Purchase

    1st month just put on dog two days ago so have not been able to evaluate as of yet. Gave two stars for packaging and convience.

    Thanks for your feedback!

    Didn't work for us

    Posted by YoungerNextYear on Mar 02, 2016 | Verified Purchase

    I thought maybe this product would work and that I would be able to order from iHerb instead of making a special trip to the pet store but unfortunately, it isn't strong enough for our dog.

    Thanks for your feedback!
