## Questions & Answers

**Q: Has anyone used this product in the Pacific Northwest and had any luck?**
A: Its awful, I put it on two of my dogs and they scrached and itched for months.  I was beginning to worry, but after 4 months they stopped.
Do not buy this product.

**Q: Do you carry braveto fla and tick chewables for a 4lb. dog**
A: Thank you for your question, currently we do not carry any oral flea and tick medications.

**Q: What is the shelf life of product?**
A: Pkg is trashed so I'm not sure.

**Q: Which one should I use for a 13 week old Pitbull puppy?**
A: All the flea and tick medicine are bases on weight. I would recommend that you weigh each puppy and buy the one closest to the weight requirement. Now some are for puppies. If they don’t have the one you are looking for go to the weight. It is always better to go with a lighter weight then to have no medication for this issue

### ⭐⭐⭐⭐⭐ Flea and Tick repellent

The product was simple to use. Open vial and apply to dogs back.

### ⭐⭐⭐⭐ My absolute go to for fleas
*by R***G on March 14, 2025*

I have tried ALL the "generic" Frontline on here. This is by far, the best one. The Amazon brand made several of my cats lose fur and break out. Smelled absolutely horrible like a fishy scent. This one did not. The others only keep fleas off for about 2 weeks and did not kill eggs because I kept finding teeny ones. Like fresh hatched. This one worked and killed all fleas. Lasted a month and did not smell strong. Will keep buying. Just like Frontline at a better price. (
