I had 2 dogs that were both infested with fleas. My big dog was even creating bald spots on his legs from chewing. I tried other products with NO RESULTS!!! It is incredibly frustrating when a product doesn't work, the dogs are miserable, and you are stuck waiting another month to try something new so you don't poison your pets! I finally bought K9 Advantix II, treated both dogs, and within one week a thorough combing with the flea brush revealed no live fleas on either dog!
Pros: easy to use, effective

This product is useless. Its been 4 days since I have applied it and my dog is still covered in fleas. I paid 30 dollars for flea medication for nothing. Now I have to spend even more money to buy something else. This is ridiculous.
Cons: price, didn't work

my dog is only 25 pounds and he has fleas but he doesnt have them badly. I gave him the k90 advantix and he is still itching. He's not itching as much as he was. But I still see a nest on him.
Pros: easy to use, price
Cons: didn't work
