These are pants to be worn over diapers or sanitary pads for dogs. The waist is adjustable with Velcro. There is a hole for the tail. They come with suspender-like straps that go over the neck to prevent them from slipping off. When a female dog is in heat, dog-specific pads can be expensive, so using human pads attached to these pants is a more affordable option, and it prevents messes on the floor. These are items that are not often found in pet stores. It's also cuter to put pants over diapers. The size is not specified, but my dog is a medium-sized dog of about 5 kg. They have been used only a few times and are in good condition. Please understand that these are items stored at home before purchasing.
