Question:
Why isn't the K-9 Advantix I put on my dog working? I put it on her exactly as the instructions read???

A:  I recommend using either the Advantix or Frontline topical products every 3 weeks through the warmer months (March - Sept/October).

The fleas have been terrible this year! The past few years have produced a large number of fleas.  Until we get a good, hard frost, the flea and tick population will continue to multiply!  Because of the increased load, the topical products are being challenged.  Both Advantix Adan Frontline weaken during the fourth week of application.  This is why I recommend re-applying every 3 weeks.  Both products are safe enough to use every week, if necessary.  Make sure your dog doesn't swim or have a bath for a week after application.

I would also recommend ensuring that your house does not have fleas as well, this could be a cause of re-infestation of your dog.  The Knockout spray, is the best product on the market for treatment of your house.  Walk around and spray the entire house (over furniture, under furniture, in closets, on bedding, etc.), then vacuum and you're done!

If you continue to have problems, I would recommend trying the Frontline to see if you have better results.  The two products have different mechanisms of entering the skin.  Dogs will dry skin may have more sauces with one of the products over the other.
