does this work against biting flies?

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.

My girl back andd forth between 53-58#, which one should I get?

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.
