If a dog barks, it may be because he has seen something unfamiliar and is scared. If your dog keeps barking at a guest coming to your home, you should give the dog a command to stop barking, and then take the guest's clothes or belongings to let the dog smell it to familiarize it with the guest's smell. If the dog is quiet and doesn't bark, reward the dog with a small treat. When the dog can get along with the guests, the owner can guide the guests to try to interact with the dog, and even feed the dog some snacks.

When the dog keeps barking, the owner can use toys to attract the dog's attention. Hold the toy that the dog likes in your hand and give the dog a command to sit and then give the toy to it. This will attract the dog's attention and he will stop barking. If he behaves well, he can give him snacks. Indicates reward.

Unneutered dogs will have a strong sense of territoriality, so neutering a dog can reduce the territoriality of male dogs and reduce dogs from making bad behaviors towards people. Neutering can extend the dog's life, change the dog's personality, and reduce the dog's habit of wandering, peeing everywhere, and howling.
