This is a dog training circle for toilet training. I used it for a few months after welcoming a puppy and before letting it roam freely indoors. The tip of the protrusion used to secure the tray has been chewed and has a hole, but I don't think it affects use. I cannot ship it, so please purchase if you are able to pick it up. ^ ^ - Brand: Petio - Model Name: Dog Room Circle - Size: Please refer to the photos - Features: Designed for toilet training - Color: Dark Brown ※ There is no roof. ※ I will also include the pee tray. I am located in the southeastern part of Osaka City. Thank you. m(__)m
