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.

Frontline plus would be better option.
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.

Worked great!
We have 2 large dogs that I used this on. I’ve not used this brand before and I’m really happy with my results. I waited late into summer before we treated the dogs and I have to say that I was really happy with the results!! They weren’t infested , but they certainly had a flea problem. It was a great value and worked really well. I do need to reapply as it’s still flea/tick season but I’m certain it’ll work just as well as the first application.

Horrible Product
I have a German Shepherd Puppy, who was 4 months at the time of treatment. I purchased this product to help alleviate the fleas and whatever may have been causing him to scratch. Well, after 7 days, he began scratching as if he had not had any medicine. I ended up giving him a second dose around day 15 because I did not want to give it too close together. Barely a week later, he as sctratching again. Do not waste you money on this. Frontline used to be a good product, but I would recommend Revolution or some other product because Frontline is not where it's at.

Think about it
Just take your animal to the vet. This stuff works in a pinch but in 3 days you'll have the same problem. Its requires no prescription for a reason.
