About FRONTLINE Shield for Dogs

The #1 Name in Flea and Tick Protection*

FRONTLINE Shield is powerful 3-in-1 protection for dogs. It not only kills fleas and ticks—it also repels mosquitoes, ticks and stable flies. Just one dose provides protection for a full 30 days.

Breaks the Flea Life Cycle

FRONTLINE Shield kills existing adult fleas as well as flea eggs and larvae. Once applied, it rapidly spreads over the surface of your dog’s body. One application provides continuous flea and tick protection for a full month and helps prevent future infestations.

Protect Your Dog So You Can Go Anywhere Together

Fleas and ticks can be found everywhere outdoors—the park, the lake, even your own backyard. That’s why monthly protection is so important.

From the #1 Name

FRONTLINE is the #1 name in flea and tick protection.*

Repellency Power

Repels ticks, mosquitos and stable flies, so they won’t bug your pet.

Kills Fleas and Ticks

Fleas and Ticks Abound Year-Round

No matter the time of year, fleas and ticks can pose a threat to your dog.

That’s why you need monthly protection year-round with FRONTLINE Shield.

visit your vet before writing bad reviews

These pets may have allergies\atopy. Getting rid of fleas is just the first step. A vet visit is required to rule out skin allergies and or food allergies. One product is not going to be a miracle cure. Many pets have skin allergies ,food allergies ,environmental allergies. Allergies are not easy to treat, usually it takes a combination of several treatments, medications and often dermatologist visits. I was a CVT for 20 years and have seen horrible cases improve with hard work mainly from the owners. The DVM’s have a treatment plan, but lack of client compliance is usually the reason why the pet never improves. Or, owners google their pets diagnoses and buy useless products JUST MY OPINION

Great for repelling mosquitoes

There are so many mosquitoes this time of year and this product really helps repel them as well as kills fleas and ticks! Now I can take my pup with me anywhere this summer and not have to worry about her scratching.

Frontline for fleas

Only applied once as yet. Seems to work well. Easy to use. My dog does not mind it being applied.

I decided to give frontline a try again only to be disappointed. The dogs have more fleas on them now than before and sadly in an attempt to fix the problem, I've now used two packets in 5 weeks with no resolution.

Fleas be gone

I have a 12 year old 3lb York is. These drops keep her flea free and she loves me for that. I recommend it.

Burned my Maltese

I have a 6 lb Maltese and she has had a very bad reaction to this product. Her skin is burned and she is definitely in pain. I have contacted my vet and am trying to get this cleared up for her. Definitely would not recommend for a fair skin dog. My black shitzu mix does act as though the application site is annoying him, but he has not had as bad as a reaction, thank goodness.

It dose not seem to be working.

I gave it to my dog on June 29th. It was 12 days ago. I do not see a difference in her behavior. She is still chewing her toes, and scratching herself. She lays on her back and wiggles around. In fact, she is doing those things even more. I am very unhappy with the results of this medicine.

Our dog weighs 2 1/2 pounds.

Our dog is about 4 months old but weighs only 2 1/2 pounds so this scares me. It was recommended by our Vet so I’m sure it’s safe. Just the same, we will take her to the Vets to have them administer it. To be safe! Can’t take any chances!
