This is our first time using YT, find the site very interesting and helpful thus far. Yesterday, I bought a 3 mo supply of Bio Spot Defense (Tick & Flea) to use on our 1+ yr old yorkie. We have always used Frontline with success, but the expert at the local feed store talked me into trying this. My wife said to ask about it on this forum. Any feedback, good or bad is appreciated!
