FRONTLINE Shield Flea & Tick Treatment for Large Dogs 41-80 lbs. Count of 6

Definitely the best flea prevention drops we have used. No adverse reaction on our 3 dogs and not a single flea in a 6 pet household.

I have tried all different brands of flea medicine for my dogs and I always end up coming back to Frontline. It works better than all the other brands. It might cost a little more, but it’s worth every penny.

Worked well to kill fleas and ticks. Easy to use, they are chews

My dog has had fleas a few times. When she has had fleas I get this stuff. After using this and also doing lots of laundry and vacuuming, the fleas were gone within two weeks. Once my dog went to a friend's house that had a ton of fleas. When she came home, she picked up a flea or two but they were all dead by the next day so I know this stuff works.

Best price for a very effective flea med. Highly recommend this product.

Old packaging much better, new one gets product all on you hands.

This is the best flea medicine I've found on the market . I had a mild flea infestation that bloomed over night into a full blown massive infestation and I tried k9 advantage and it didn't work. I tried front line plus and it took longer to kill the fleas. But the front line shield gave instant relief to my dogs. I combined front line shield along with flea and tick home treatment made by Black Flag and vacuumed 3 xs a day and within two days the infestation was gone. You have to pay attention to when its time to give your dog the next monthly dose because protection ends exactly in one month. Or you will have fleas on your dog again. I treated my yard several times and I don't care what anyone says. You can't get rid of fleas outside 100 % . your pets will get fleas again without front line shield. Best flea medicine on the market that kills the fleas instantly. My dogs had instant relief from itching and scratching.

Pretty ineffective. Word on the street is that the fleas have become immune to this older product
