Usually we shave before bathing. That is because we then get all loose little hairs off in the bath to avoid itching and skin-irritation.
Face, feet, and tail is shaved. Also genetals. Do be careful, the blades get warm.
Also pay attention to the nails. Some need to clip them every week.
Before bath, make sure the dog is proparly brushed and combed, there should be no tugs at all, as they will get worse when wet. Also make sure the ears are clean. If hairy, pull the hairs out. Use earpowder, and pull just small amount of hair at a time.
For the bath, it is advisable to use dogshampoo, and conditioner is often needed. Make sure to rinse thoroughly.
For best result, and to make sure no loose hairs are left in the coat, use the blowdryer. Be careful not to overheat. Brush/comb while blowing, for a neet finish, making it better to scissor afterwards.
