FrontlineShield Flea & Tick Treatment for X-Large Dogs 81-120 lbs. Count of 6

Works on both ticks, fleas, lasts more than 30 days

Works well. Easy to apply for the most part! Doesnt completely get rid of fleas, but we've only been using for a week. The scratching is definitely less.

Great for killing ticks and fleas although fleas are not much of a problem around here. Repeals mosquitoes, too. Unfortunately it does not last a full month on ticks, more like 3 weeks, since my dogs swim almost every day.

Ordered this by mistake, but it is working, easy to apply and didn't affect my dog. Some flea/tick products can really affect your dog, talk to your vet about the best, safest products to use. You and your dog will be happy.

Have this on subscription for my two dogs to use as a supplement for their vet treatment. Ticks are seriously epidemic this year. The combination means no ticks or fleas…the girls are inside/outside dogs.

This product does not work. I have used Frontline brand for YEARS. My dog has fleas. My house has fleas. I have flea bites! I had to buy more product and this one is out of the return window. I also had to bomb my house! What a disaster and additional expense. I am going to write directly to Frontline.

It's works, but not nearly as good as had hoped ! Effective for about 15 days !

During a hot summer with fleas this helped get them under control.
