Shears are used to thin and shape the coat and trim long hair in sensitive areas. Thinning shears are blunt tipped, toothed scissors with slightly curved blades. This makes them ideal for trimming hair around the anus, the ears and muzzle. Thinning shears are used to blend clipped hair into scissored hair and clipped hair into unclipped hair. Thinning shears can also help the coat lay flat along the back and sides of the dog and can generally help keep your dog tidy between clippings. Thinning shears come in many styles. The finer the teeth on the shears, the softer and fuzzier the dog's coat will look. Ask a grooming professional which type of thinning shear is appropriate for your dog's coat.
