Undercoat deShedding can be performed at any time on a pet with a completely dry coat, but for best results, it is recommended to be performed immediately after washing or drying. KOKIWOOWOO brand's extensive line of grooming products are designed to promote healthy skin and coats in pets, and significantly reduce the amount of hair that is being shed into the house with regular use. Before using the undercoat deShedding tool, perform a complete physical inspection of your pet. Look for sores, bruises, and skin conditions, which your pet’s coat may conceal. If your pet has any of these conditions, seek treatment from a veterinarian before brushing. In addition, before using the undercoat deShedding tool, remove tangles or mats with KOKIWOOWOO Fur Dematting Tool or Grooming Rake. Use the undercoat deShedding tool much like a brush, gently stroking across the pet’s coat in the direction of hair growth, angling the stainless steel teeth towards the coat. Start from your pet’s head and work your way back, using extra care near the stomach, legs, genitals, and anus. Avoid making excessive strokes in a single area, instead of using fewer long, gentle strokes up and away from your pet’s skin. Although the Skinguard design prevents digging in at edges and helps the undercoat deShedding tool slide over skin, deep or rough brushing can still irritate pet skin, so avoid brushing with excessive pressure. If you notice any redness or irritation discontinue use.
