Shaving your dog’s coat – should you or shouldn’t you?

There are several different types of textures on dog’s fur, but in a general breakdown there are two coat types; single coated and double coated.  A single coat means that there is only a top (or over) coat that grows all over the body with no different undercoat.  Breeds such as Shih Tzus, Poodles, Bichons, for example, are ones with a single coat.  These breeds can be shaven generally with the only thing potentially occurring to the coat is over time it may become softer or it may have a slight colour change.  Even with only a single coat you want to be careful on when you shave them, especially if you shave them right down, as this, although may appear to feel cooler, leaves the dog exposed to the possibility of sunburn.  A dog with a coat shaved right down in the height of summer should not spend any length of time in direct sunlight.  With the simple fact that there is only one coat the hair grows back normally and even after a shaving.
