I paid 36 dollars for a four month supply of Advantage at my vet the other day. If I had only bought one month, it would have been 11 dollars. It is a flea medicine that you put on their neck in the back or high up between their shoulders after you part the hair to let it get on the skin. You have to put it where they can't lick it off. It comes in a little tiny tube and is great. i don't think you can buy it ovr the counter but you do not need a script for it. Just get it at your vet. You apply it once a month. |
