This is a perfect set for toilet training and preventing biting in dogs. I bought and tried this set when I got my dog, but it didn't work for mine, so I'm selling it. You can see the remaining amount of the bottle used for preventing biting in the second image. The toilet training spray cannot be confirmed due to the packaging, but I used it about 10+ pumps, so I think there's about the same amount left. In the third image, you can see that the stopper on the lid of the bottle used for preventing biting is broken. To prevent leakage, I will ship it with tape sealing the stopper. I remember the regular price was about 1000 yen each. I hope you will consider it.
