Great

[This review was collected as part of a promotion.] I got this because I have two Australian shepherds and I love them like they are my children and only want the best for them. FRONTLINE® Shield for Dogs (Medium) Is absolutely perfect for the size of my dogs

Working great!

[This review was collected as part of a promotion.] I got this 3 month supply of Frontline small dog flea and tick treatment and it is working wonderfully! We live on a farm and ticks are horrible here but these seemed to just make them fall right off!! I will definitely be recommending this to all of my friends and family!

WONDERFUL for our English Mastiff!

[This review was collected as part of a promotion.] So very happy with the quality of Frontline. We use every product possible for our many animals because I KNOW I'm getting a quality product. We have several acres in the country, so pests are always a huge concern for our boys because they run freely, and then come in the house. I'm aware that some people have had issues, but we've been a consistent Frontline customer for many many years and I have NEVER had an issue with any of their products for our fur babies.

Thankful for this!

[This review was collected as part of a promotion.] Love the peace of mind that comes with a product like this one. My dog loves being outside, but obviously so do the critters, and living right by the woods that makes me nervous. She's a golden doodle, so it isn't always easy to spot things in her fur, and I'm always anxious that there's a tick hiding somewhere. This product makes me feel much more secure.

Another great Frontline product.

[This review was collected as part of a promotion.] We have used Frontline on all od our dogs for years, and we know it woks well. What I really like about this product is it is a bit less oily upon application, and our two dogs that seem irritated by flea medicine on their necks seem much less affected with thi new product. A winner!

This product is for dogs only! comes in different weight classes so be sure to weigh you dog to get proper dosage. It's a great product. kills and protects against fleas, flea larvae, ticks, mosquitoes, etc. for 30 days per dose . The only downfall is that it's greasy on the dogs' back area after application, but you can bathe dog after waiting a full 24 hrs after application. Read full instructions before use.

Disappointed

[This review was collected as part of a promotion.] Honestly not quite sure I like this product. Am a little afraid to use it on my dog as looking at the ingredients makes it seem unsafe. Honestly I can not say how well this product does or doesn't work.
