We gave Buddy a bath today, he doesn't look very impressed, but at least he smells nice now. Because he is mainly an indoor dog he doesn't get very dirty or smelly. So far we have found that if we bath him properly about once month it is enough. Although if he has played in mud at the park we give him a quick wash in between times. We also have a professional groomer once every three months, so he gets a really thorough washing then.
