Ziggy may not play guitar (sorry, David Bowie), but neither does he do much in the way of shedding. All dogs shed to some extent, but short-haired breeds shed so little it's almost impossible to tell they are shedding at all. Yet, despite this, Ziggy still needs to be groomed on a regular basis. Not only is this is a good way to keep the dirt and dust out of his coat, it is a good time to examine him for parasites, cuts, nicks, bruises, and skin ailments, some of which might require a trip to the vet.
Ziggy is just your average dog, he loves life, he loves his family, and most of all he seems to be happy with the way he looks (not that most dogs really care). But at the same time, if you don't take care of the weekly grooming and monthly bath, you are going to end up with one stinky pooch.
Even minimally shedding dogs need to be groomed at least once a week to remove dirt and debris from their coat. It gives you a good opportunity to check the skin over for fleas, ticks, and any injuries. Make it fun for both of you and let it become a great bonding experience.
