I used this for about a week after my dog's neutering surgery. It's convenient because they can urinate and defecate while wearing it. It's so cute that I'd like to use it as everyday wear, but my dog doesn't like clothes, so I'm selling it. The size is NM, please check the size chart in the photos (the tag has been cut off). I heard that if it's too big, the elimination area will shift, so a perfect fit is recommended. For those who don't mind used items. #khaki #full of vigor #post-operative clothing
