Also, the lace design is made from pleasant quality cotton thread that you and your pup will love to listen to. 3、MULTI FUNCTIONAL ACCESSORIES: This dog doorbell doesn't just hangup on the door handle. With its versatile regulable door release, you can easily attach your puppy supplies to the sliding door handle. It can also be used as an outdoor button for your dog. 4、REGULABLE: Regulable essentials are ideal for any size of the dog or the height of the door. The length can be adjusted easily according to your pet size.

You can start training your dog by pointing at the bell, saying 'ring' and rewarding them when they have completed the action. After doing this a few times, do the same steps again, but this time, reward your dog outside your home until you can confidently guide your pet to the place you want him to pee.
