Very Dissatisfied
I have a Shiba Inu and previously I had been using Frontline with no problems. I put the K9 Advantix on him on a tuesday and when I came home from class thursday he was freaking out hiding in my closet (he has never been in my closet before). He was panting heavily and didn't want me to touch him whatsoever. Anytime I made him get out of the closet I noticed he kept trying to bite something on his back.. I'd imagine this was his skin becoming very irritated. I had no idea what was wrong with him until I realized the only thing I changed was his flea medication. The effects wore off by the 3rd day, but I was afraid for his life. I tried calling the number on the box.. I left my name and number, but no one returned my call. I will never use anything by them again.

Least expensive on Amazon
This particular brand seems to continue to work for my two furbabies although it may not last a full month sometimes. And, at just a tad over $10.00 a monthly dose, Amazon is the least expensive especially since shipping is free.

Satisfied
Got what I ordered and in a timely manner. A much better price than the "Chain Stores". I will order from here again when my supplies run low.

It's Flea control
So the item got to me, but it took a very long time, I think it was lost in the mail. but it's flea control for my dog, it got here and all is well.

good product
Well, so far the product worked well on my puppy....for the first few weeks. I found a flea on him the other day but I think it's because I took him to a dog beach and he was surrounded by other dogs. He keeps scratching himself but I can't find fleas!
