As the name suggests, this product easily catches the droppings of your beloved dog who has trouble with toilet training. My elderly dog uses it, and it's very useful (I can't do without it, not only at home but also when traveling). The M size Unkoro Catch fits waists of 30-46 cm and is ideal for dogs weighing 6.3-9.9 kg. - Product Name: Unkoro Catch M size - Condition: New, unused - Size: M - Waist Size: 30-46 cm - Weight Range: 6.3-9 kg Dedicated urine-absorbing pads and odor-proof bags are not included. (At home, we use commercially available sanitary pads from drugstores or regular plastic bags as substitutes, and they work without any problems.) I will ship via Mercari delivery within 24 hours. Thank you for looking.
