Rated 5 out of 5 by K9 Great As usual a great product and efficient service. Thanks for helping save money too. December 9, 2014
Rated 5 out of 5 by Works great! I live in the middle of a forest in CT (near Lyme CT). My dog just had her annual check up and she's Lyme disease free for the 3rd year in a row! I'm always checking her if she bites a spot on her fur and I've never seen a tick bite her. December 5, 2014
Rated 5 out of 5 by Works on our dogs and on my cat We used Frontline for 4 months and the "kids" kept itching no stop. We switched to K9 Advantix II for our 10lb female and 25lb male dogs. And K9 Advantix II for Cats for our 15lb Siamese princess cat. In less than 12 hours all of the itching stopped completely. And last week (the day after Thanksgiving-Friday Nov 28, 2014) a very skinny young female chiuahuah showed up in our yard....absolutely covered in fleas (fleas 2x the size of a grain of rice! Gigantic fleas!).. seemed like a thousand or more! We bathed her and gave her a K9 Advantix II treatment. Less than 5 hours later, not a live flea to be found. This stuff is very effective!!

Rated 4 out of 5 by Lots of Scratching Bubba is outside a lot and I think he was being bit by insects. He was always scratching. After taking Advantix for a few weeks, the scratching has stopped. He still takes his heart worm medicine that has some flea repellent. November 21, 2014
Rated 5 out of 5 by Good Choice I've been a Frontline user for years. But switched to K9 Advantage as Frontline wasn't helping with Flea. I put K9 on and after a few days the fleas were gone November 12, 2014
Rated 5 out of 5 by Good product Medication works for us. Only thing is my vet said to apply it every three weeks, not four, so it gets kind of pricey. Beats having ticks or fleas. November 9, 2014
Rated 5 out of 5 by Great for dogs Not so good for humans!! Easy to put on your dogs and works well! Wife will yell at you if you put it on your kids! November 6, 2014
