I am a groomer and I only use OSTER TURBO 2 speed clippers. You will need multiple blades specific to your dog’s fur. Purchase a grooming book or buy a video. You must be very careful in the hind leg area. You must pull the skin back lightly so no to catch it. Rule number one before you do anything is comb through all hair with some water or conditioner and get ALL knots and mats out FIRST, then bath him downward, Head first, Hold his ears down close to his body to prevent any water from getting into his eyes, I put mineral oil in there eyes first before bathing. You can purchase a dog dryer too. A human dryer will dry out the fur. Consider hand clipping the hair in sensitive areas with a good hair scissor. Tie the hair up away form the face or you can cut bangs and angle the sides.
