2-in-1 Dog Bark and Shock Collar

2-in-1 Dog Bark and Shock Collar Features: waterproof and rechargeable. Has many settings. You can use it as an e-collar for training. Can also be a bark collar - can use with sound aversion or vibration for people who do not want to shock their dog. This trained my puppy not to bark in 1 hour with sound alone. Condition: Gently used. Some scuffs on remote and collar. My puppy who previously used this is hypoallergenic, non-shedding, dog.
