Review: Thank God for front line! - I should have went with my gut and bought this the first time. In the past I have always used front line. My animals went without flea medicine for a few months so when I finally had the money my house and pets were infested. It killed me to see the whole house uncomfortably miserable so I went to the closest place to my house witch was a feed store, all they sold was advantage. It didn't matter to me at that point and I heard that was a good product. What a disappointment especially for the money. The fleas were gone for not even two weeks. Then I tried pet armor I swear I used it before and it worked? Not this time no way three days later the fleas came back! With vengeance!!! and did I mention that during all this bull I've been treating the house as well? By now I've thrown the towel in. I'm so astatic to say that after I purchased the front line and administered it my animals and my house are flea free! My animals are so happy and relaxed. Thank you so much front line, I'm never leaving you again.

### ⭐⭐⭐⭐⭐ Thank God for front line!

### ⭐⭐⭐⭐⭐ Works great
*by M***S on September 5, 2025*

Product works well on my dog. Doesn’t stink or cause my dog any skin issues.

### ⭐⭐⭐⭐ Frontline plus would be better option.
*by M***7 on September 16, 2025*

Works ok. The frontline plus is a better option though. The traditional frontline hasn’t worked 100% in years. I used to be a dog groomer so I know this to be. Any flea and tick med that you can purchase without a vets prescription is not going to be 100%.,They at one time did make it for prescription, but fleas become immune to these protections so the vets don’t utilize any longer. Hence the reason you can now buy them. I suggest either frontline plus or Avantix with a Serento collar together.
