## 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.
