I have a 20 lb cockapoo and I would like to leave his coat a bit longer in the winter but we live in NH and snow is a given. Going out in the snow can cause some rather large snow balls to build up on Elvis. Is there anything you can spray on the coat that would keep the snow from sticking to him? He has a "snowsuit" that covers his belly, chest and part of his front legs which does help. But the exposed parts of his legs get covered.
