You found this problem, which proves that you are tired of dog harassment, but you should actually ask this question. Dogs have become dumb, so they can only cut their vocal cords. People can't stand it. Why did you think of letting it cut the vocal cords? Some of them poisoned the puppy with drugs. In case the medicine doesn't work, the puppy may be gone, so the safest way is to educate him. Don't indulge him when he quarrels, but beat him and reward him when he regains calm, so that he can be trained several times and basically stereotyped. But my dog has been a dog for a year, and my family will give him food when he quarrels. I can ban it three times, but not for long. Some time ago, the puppy almost collapsed because of too much noise. I kept this teddy for a year, and this teddy kept quarreling until I found two small keys. First, even if you don't play, keep it around or at least keep it away from the wind and rain. Second, you should buy it a bark stop. It hurts. If you get used to it, just tie it loosely, about twenty or thirty. Don't be stingy with money. If you can really live for twenty or thirty years, try not to give up raising. I hope there are not so many stray dogs in the world.
