Cooler temperatures signal more pleasant days for outdoor pets (and people). But indoors or outdoors, protect all your pets with medications for fleas, ticks, and heartworms. If you buy a 6 month supply of the Frontline Plus or Revolution you will get one month supply free, and if you buy a year supply of the Heartgard Plus we will send a coupon for you to get a $5 rebate check in the mail from Merial.
