I'm assuming dr._ learned that quickly lol, I resigned before I could find out. Good to know about the Revloution in case anyone I know askes me about it, we don't really have heartworm here (a handfull of Katrina rescues brought a few cases up, but that was it) so it's not commonly used anyway. I like Heartguard better anyway since it protects against roundworms which is common because of all the wild critters that hang out in everyone's yards lol. That's why I stick with my tried and true Frontline/Heartguard combo
Thanks for the info
