Cutting the dog's vocal cords will have a certain effect. Vocal cord surgery is an operation to remove part or all of the vocal cord tissue of a dog, in order to make the dog unable to speak. This kind of operation is generally to solve the problem that dogs bark too loudly or too frequently.

Vocal cord cutting will cause the following effects:

1. No barking: Dogs don't make sounds, and they can only express their needs and emotions in other ways.

2. Dull: Surgery may cause some sensory loss or discomfort, making the dog dull or listless.

3. Respiratory system problems: Vocal cord surgery may have a negative impact on dogs' breathing, because vocal cords play a certain role in preventing food and liquid from entering the respiratory tract.

4. Tracheal problems: Vocal cord cutting may cause tracheal injury in dogs and increase the risk of tracheal problems.
