This is a perfect set for toilet training and preventing biting in dogs. I bought and tried it 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 it seems that about the same amount remains. In the third image, you can see that the stopper on the lid of the bottle used for preventing biting is damaged. To prevent leakage, I will ship it with the stopper taped. I remember the regular price was about 1000 yen each. I hope you will consider it.
