My sister purchased this product for her 15 lb dog.  He stays with me on the weekends and in the last few months, I noticed that he was always itchy and always licking and chewing his fur all over his body.  During baths I noticed he had multiple red spots where he was bitten.  Lately, there would always be 2-4 fleas in the bath tub and last week I found a tick on his face.

We checked with our vet and she said products sold outside of the vet's office are not effective.  She has not come across a single success story amongst her clients regarding use of these products purchased online or at big-box stores.  I speak from experience...do not waste your money purchasing these products online.  They don't work.  More importantly, don't put your dog through so much misery and discomfort or place them at risk of illness from disease carrying pests.
