Never used the oil I've been out there an picked it. Depending where you live you'll find it. Just soak the leafs in a bucket only put a little bit of water into soak up in the leafs then wrap the leaf round the area then the vet wrap an leave it over night. With dog being outside it should stay damp the vet wrap. If indoor just keep checking it to makesure it's still damp mate give it a few days should get to work.
