Dogs, just like us humans, tend to get dry skin specially during Winter.  There are many things that I could recommend such as: changing his food, running a humidifier, making sure he is drinking enough water, etc. to avoid dry skin, but do you know what?  This is the one thing, above all, that will keep your dog from having dry skin: brushing him once a day, at least.  Yes, that’s it!  Brushing him once a day.  Very simple.
