【Dog Training】 With a small instruction manual. Brand new, unused, and stored at home, but taken out of the outer bag for photography. Shake it with a "gasha-gasha" sound, and the owner hides it and makes the sound. The dog is startled by the sound and recognizes it as an unpleasant noise, and quiets down when the sound is made. It's also effective to make the sound near the dog's ears, as it will be startled. This training eliminates unnecessary barking. This is a spare item I purchased and kept. Although unused, there are some minor bumps and imperfections. There is some dirt or discoloration on the connection at the bottom of the can. Since it cannot be posted, it will be sent by standard mail or similar, so the shipping cost will be a little higher.
