Listen up folks...
Listen up folks, this flea medication will not give you the results you are looking for, overnight. So please don't expect to see immediate results. If that is what ur looking for, maybe you should seek a vets treatment. Because this is above all, the best flea medication for rhe money! You really can't beat the price. This stuff takes a good Week to start completely keeping your furbaby flealess.. and I know we have fleas in the yard.. and there ARE NO FLEAS on my babydog! My Yogi Bear has flea dermatitis, and he chews, chews, and keeps on chewin til he's a giant scab. Fortunately I gave this medication another try for a longer period (about another week) and I'm SO GLAD I did! My boy is so much more calm and relaxed now that he's not infested with aggervating fleas! Whoohoooo! Shout out to the makers of this medicine!

Works at first, but then it doesn't.
It seemed like it worked at first.. the pets were itching more within the first several hours and by the next day, the itching had stopped. We had a great first couple of days, but by the end of the first week, the itching started again & upon further inspection- all of the pets still has fleas. I understand that it's normal to still see a flea or two on the pets bc they may be a new arrival and/or hadn't come in contact with the product, etc.. but the fleas we are seeing were in the usual areas on our pets that fleas typically like to hang out (like on their necks, stomachs, near the tail, etc), all the time. Also, our pets started itching again.. I know that with Advantage/tix, sometimes it takes a few weeks for the product to distribute throughout their fat or something like that, but from what I've read, this product is in the hair? So I don't know. I'm going to dose them again in a couple of days bc it will have been 2 weeks since the first dose. I'll update with our findings after then!

Quality Product
This product is less expensive than Frontline, but has worked well on my 3 Life Stock Guardian dogs. They are exposed daily to ticks and fleas. I have found no fleas or lice and only dead ticks on the dogs.

It works a little while then quits! It seems like a lot of flea and tic meds are not working well!

No fleas, saves money.
We buy largest size for our chihuahua and put one vial in glass ampule with lid. Use 0.5 ml per month which is the dose in the small dog size. All sizes are the same ingredients and strengths. Saves a lot of money. Keep a note book of treatment dates.
