Advantage II Medium Dog Vet-Recommended Flea Treatment & Prevention | Dogs 11-20 lbs. | 4-Month Supply

We have a Cairn Terrier. She is about 15 pounds. She had fleas for the first time in 11 years. We first tried a popular flea killer that uses Fipronil. But, many fleas have some resistance to Fipronil, and I could see live fleas on our dog after using this the Fipronil product so I bought the Advantage II. I did not want the extra ingredients to kill ticks, etc… so that is why I did not use the Adnvantix. I applied the first two treatments 10 days apart. The instructions allow for quicker initial back-to-back applications to get a good jump on a flea infestation. After that, we went to once a month. Our dog did not have any side affects that we could see. And, after the first two applications, we no longer saw any live fleas on the dog. One suggestion that I have for those that have a dog with a flea infestation: Shave or cut the fur as close as possible and then give a good flea bath. This will get rid of any eggs sticking to the dog’s fur (you’ve removed most of the fur and washed the rest). Make sure everything is dry before putting on the Advantage and then do not allow the dog/cat to get wet for 24 hours. That’s about it. It worked for us.
