Review: This is the best flea treatment so far for my 5lb chihuahua. Just like humans every dog is different so it’s important to find what works best for your pet. My dog has epilepsy and a heart condition and has no irritation with this medication and it works immensely better than frontline. I think the fleas in my area are immune to frontline so that could be why it doesn’t work. Same for my sisters cats, frontline doesn’t work either. Advantage works the best for getting rid of fleas. I was told to use a different medication each month so last month I used frontline and my poor baby was bitten up. She might have had about 5 fleas on her but it still makes a difference and about 30 minutes after I put on advantage she’s feeling better. That month was horrible for baby. I’m glad we’re sticking to advantage now. But remember every dog is different and fleas in your area might also have immunity to certain formulas as well so it might take time to find the right flea prevention for you.
Review: Been using on my Yorkies for years with no problems. Recommended.

## 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.
