30-60 pound dog is 13 to 15 cc's or mils if it is the formula with the 1.47%...double it if it is .75%...not telling you how to do it...this is how I do it and it keeps the fleas off for quite a while...just make sure the other contents in the bottle are inert ingredients... also make sure you don't buy the bottle that comes with fertilizer...
wear rubber gloves when rubbing the product into the dogs back...
so you dont dilute at all when putting it on the dog?? as long as its 1.47%
if you are going to dilute it then I suggest you measure out what you need first... then dilute it if needed...The 13 cc's I was talking about is straight out of the bottle...this method has worked for me...
