Great product that I use on my four dogs, I never have a problem with all the little critters that creep me out. It is long lasting, my dogs don't seem to have any bad reactions to the product, my only problem is the cost.

These are really pricey but it's the only brand I get my dog. They even have them at the vet. I've been needing to get this again.

This worked on my dogs when the apartment I was in was fleas. Love this product! It kept them off my dogs so they weren't tearing up their beautiful coats.

Have used this product for many years on my dog. It works very well.

Our vet actually stopped carrying Frontline this year - they say that fleas have adapted to the formula and it's no longer as effective, and therefore they can't offer it to their clients. Terrible news for us, as this was the only topical flea and tick preventative that my Corgi wasn't allergic to! :(

love this it really works well

Having 3 dogs this can get pretty pricey, I would have liked it to work better. After only 2 weeks of applying this to my dogs. they were scratching and had fleas. I had to wait 2 more weeks before purchasing a different brand that at this moment seems to be working better.

Horrible chemicals, and doesn't repel so the dogs bring in ticks

We live in Southern Ohio in a Suburban area. I have a mini schnauzer who is 7 months old, under 20 lbs, and stays inside except to potty or go on walks at the park. With frontline, he got fleas constantly. We finally switched to heartguard heartworm prevention because it kills fleas from the inside out.

Does not work on my dogs. I wasted my money. I applied as described and followed directions but fleas were still there.

Does not work on my dogs at all. Was a total waste of money.

I was so disappointed with this product, I tried it during the summer and fleas were still running threw my little dogs fur, she was chewing herself to pieces until it was time that I could use another product which completely rid her of fleas.. I feel this product is a total waste of money.
