This is an excellent product for playing tug-of-war, which also helps with teeth cleaning and satisfies the dog's chewing needs. I think it's difficult to obtain now. I remember it cost around 3500 yen each. Although I haven't used it, there is some discoloration of the rubber and rope parts due to long-term storage. Please understand the above before purchasing. When I started keeping a large dog, I bought several, but they didn't break at all, so I ended up not using the extras. Please wash it with water once before using it, just in case. #Aririn's dog supplies
