We have found that thinning out the undercoat is key in preventing hot spots. With Newfies thick coats, if they are wet all the time, they can actually start to ROT! That can cause horrible hot spots. With Drake, we use the Undercoat thinning rake (Coat King?) and just keep him brushed all the time, checking for Dreds and matting. Also, we give Drake a short haircut and shave his belly every 4 months or so. This time of year, we leave it a bit longer because it's cold. Ever since we started doing that, the Hot spots have disappeared. They may not look like a traditional Newf, but as you can see by the pictures below, he is still quite handsome and it may help with any skin issues. Just something to consider especially if you want your Newf to swim, which something all Newfs should do.
