Great protection works very well for 30 days have to keep applying
Ticks die once they bite dog if they are protected
Bought it at petsmart
My dog is slightly allergic to it- causes itchiness at site of application but it goes away after a while and isn’t that bad

About 4 months ago on one of our hikes, our dog somehow managed to get a tick stuck on his body. After removal of the tick, we bathed and put Frontline on his body to prevent any more pesky visitors. It's safe to say that after all this time, he's still tick and flea free.

I have to say this treatment really did work ! I have a small bichon who despite my biggest effort LOVES to play in the dirt and sleep between the bushes ! So somehow flees are attracted to him ! So thank you for helping me with the flea problem!!!

After using this on my dog she got even MORE fleas. It was disgusting. I had never seen so many fleas on her. It was so disappointing to spend all that money just for it to do the opposite of what it’s supposed to.

I have a pocket beagle who has a ton of allergies. I love this stuff for fleas and ticks. Flea bites trigger his allergies so he has to use something for prevention and This was the only stuff he didn't scratch at.

This product is good and it does the job of keeping flees off but it can be pretty pricey. My dog doesn’t seem to mind it. It met my expectations, I️ would recommend to other dog owners as well since it works

I was completely blown away by this product. It seemed like such a magical concept; a pill that killed pests without any messy creams or stinky collars?! I will recommend this product to anyone with dogs!

Really like this product. I have a big dog, he doesn't normally get fleas but for some reason this season he was loaded with them. I used these flea collar and the furniture spray. they work great.

Love the sticker reminders that come in this pack. Easy to apply, Squeez on back of dogs neck. I pick it up at my CostCo and it’s a six month supply. Keeps the ticks off

Okay product I use this for my dogs and it seems to work okay. We normally use trifexis which is one of my favorite products for them but this seemed to do the job as well and I would purchase this product again
