I use Revolution on my two yorkies, It also protects against heatworms. I apply it once a month. When Layla was smaller she got fleas and I was having a hard time getting rid of them, the vet recommended Revolution, I tried it and since I haven't seen the first flea on her, After I adopted Chase I just automatically started using it on him at the same time I use on Layla. Hope this helps you some. |
