Excellent training equipment: making it easier and better for your beloved dog to communicate! What you hear is no longer the barking and scratching of dogs, but the gentle jingling of poop bells! You can teach your pet dog to use the doorbell signal when going out, using the toilet, or going to the bathroom, and then you will hear a knocking sound similar to a jingle. 3.

The connecting components and buckle points of the bell are made of high-quality materials. No matter how the dog damages it, it will not break. 4. Good sounding bells: 6 or 7 extra large bells, allowing you to easily hear your pet's natural call no matter where you are. The silver coated bell design is very tasteful and can maintain the luster of the bell. The tinkling sound is easy for your dog to hear. Dingdang bells are suitable for small, medium, and large dogs. 5. Easy to use: A simple training guide makes training easy and makes you feel like a dog talker.
