## Questions & Answers

**Q: does this work against biting flies?**
A: We had used for several years and it worked.  But last year had to take Georgia to vet for scratching.  She had fleas so this did not work.  Bad that I had ordered early to have and seller would not take the new package back. We ended with $150 bill and our vet put Georgia on Bravecto pills.  Just make sure if order 6 doses before you need since company will not take them back even though I had receipt of vet bill.

**Q: My girl back andd forth between 53-58#, which one should I get?**
A: If it was my dog I would get the 56# and up size if my dog’s weight tended more often  toward 58#.  The difference is in the amount of product to put on the dog.   The bigger the dog, the more product needed.   I would also consider whether my dog is flea allergic, and if the area has a lot of fleas or ticks.

**Q: What is expiration date?**
A: This product is a US EPA registered product, it does not have an expiration date
