Before you start clipping or trimming, you will want to bathe and brush your pet’s coat. Clipping a dirty, tangled coat is not only uncomfortable for your pet, but it will also dull your blades quicker. If your pet is new to grooming, we also recommend introducing them to your clipper before you start grooming. Turn your clipper on and let your pet check them out. This allows your pet to get used to the sound and vibrations before you begin using them.
