Fleas
It’s killing the fleas would be better if it were chewable. Beef or bacon flavored. Would make it easier use

Worked on the first dose
Worked on the first dose. All those fleas seem to have disappeared off of my dogs and cats . I did vacuum everyday and give them baths but I think the Clincher was Capstar.

My vet recommended it
My vet prescribed this at our last visit, seems to work well in the interim before the prescription kicks in.

Amazing stuff
This solved problems quickly. After a very dry summer, the fleas were horrible. My stepbrother brought their farm dog, which was covered in fleas. We ended up with an infestation. They were even biting us. I started treating the house with as many things as I could safely around a new puppy thankfully, I was able to give this to the puppy and to my senior. It took me a little over a month and a half. Between the collar, the pills and the drops on the back of the neck we finally have this fully under control. But I believe quickly with all I am the bills help the most. I didn’t give them every day. I did give them about every 3 to 4 days which seemed to help.

10000000% LOVE
I have had SO many issues with fleas this year for both of my dogs. This stuff works like a gem. I will say it does get a little worse about 30 mins after they take it while the medication gets in theior system. Once the fleas bite they get agitated and they tend to be a little more annoying but then it gets way better. My dogs will scratch and the fleas will just drop off and not even jump or will be dead. I cannot say enough good stuff about the product.
