## Questions & Answers

**Q: can k9 be used on puppies 8 weeks old  she  keeps biting her side  like something is there**
A: I would try giving the puppy a bath with Dawn liquid soap and talk to you local vet about giving this to your new puppy

**Q: Do u have one for Poodles 21 23 lbs.**
A: Use Frontline or Advantage. Advantix does not work as well.

**Q: Can anyone in florida give me your opinion on it’s effectiveness? i’m told that the fleas in fl are developing a resistance to some treatments.**
A: I live in the Tampa Bay area in Florida and used this on my chihuahua for over 3 years and it has been very effective.  I do not give him heart worm treatment since it repels and kills mosquitos as well and every time the vet has done his heart worm test, it has been negative.  Therefore, I highly recommend this product, not only for fleas, which he has never had but for mosquitoes as well.

**Q: Delivery on6-28?**
A: Hi. Unfortunately, we’re not able to answer this question. We recommend you contact the seller for more information.

*by H***M on 7 August 2024*

*** Be advised that the product is 5 star. This particular box had no affect on fleas whatsoever. All others over past 3 years work great. I recently bought directly from the company replacement boxes and those work great as usual (This particular box did not work at all. The fleas were active, happy and on furniture and people.)
