Rated 4 out of 5 by from Applied to dog, & he doesn't have fleas-must work! We received the flea and tick medicine pretty quickly in the mail. We gave it to the dog as directed on the box. I am not sure if this is coincidence or not, but the dog got the runs that evening and had to be let out about 6 times after the application. I also noticed scratching the next several days, so not sure if he got dry skin where we applied down his back. This was the first time we have used this kind on our dog (we usually get the chewables but ran out and needed something quickly). We will see if he get the runs again next month...
