PW..around here we use..oh the horrors.. margarine! Not butter, but good old margarine for things like pine tree sap, road tar or whatever else finds it's way onto Bernie's fur/pads/toe fur. I use it on my hands during firewood season, or brush cutting time. Seems to work like a charm. Rub it in like you would hand lotion or shampoo, and work it into the stuff that's stuck. Best thing is it's non toxic.. well the margarine is..or mostly lol!
