I have used Frontline Plus for over 25 years and I've never had a problem with fleas or ticks or any side effects. I have Jack Russell Terriers that want to be outside to run when it is nice and lay in the grass. Follow the directions applying in one area where it says to and you should have no issues. Remember bathing your dog often can reduce the potency of product, I bathe my dog once at the end of the month a couple days before I have to reapply and use wipes to spot clean in between baths. You may live in an area where ticks/fleas are more plentiful than the Midwest where I am and have need for Frontline Gold. Frontline is always improving their products for your pets needs>

We've been using Frontline plus, then Frontline Gold on our dog, Annie, ever since she adopted us at 4 months old! Not a flea or tick on her in all that time! Thank you!

We have been using Frontline products to protect our dogs from pests for many years. The Frontline products do their job, we never have any bug problems. Thank you Frontline!

Frontline is recommended by our veterinarian. We have used it for years. More expensive than some, but we feel it is worth it to give our dogs the protection they need. Will continue to buy.

I have always used Frontline because I believe it is safer than oral products. It is easy to administer and has always kept my dogs safe. I am against using oral products because they may cause damage to internal organs.

I've been using this for my dogs for a long time and find the product very easy to use and love the little sticky tag to put on the calendar to keep me updated for the next dosage the following month.

You might as well use water. I recently purchased Frontline Plus for two dogs. Both around 80 lbs, so I purchased Frontline Plus 3 pack 88 lb to 132 lb. After the first application, two hours later absolutely zero results. I still had one more application in the 3 pack purchase, and decided to split the last application evenly on both dogs. Today is day three and still see fleas. "Frontline Plus, waist of money and time."

I have been using Frontline Plus since I adopted Lucy 3 years ago. She spends a lot of time outside playing in the yard. Never had a flea or tick !

I've been using Frontline for many years with never a problem with my dogs. It's a great product and I'll be using this it for many years to come.

Waste of money, don't buy this product is worthless!! have used for 3 months now and fleas won't go away.
