At first, a dog will be very disgusted when you approach its food, and will threaten its owner with sounds, or even bite him. So at the beginning, you can use your hands to put a little food not far from your hand in front of it, and then gradually switch to feeding it directly with your hands. This will gradually let the dog understand that you are not a threat to its food, but a giver, so that it will relax its vigilance towards you.

Secondly, you can often put it on your hands for feeding. Open your palms and put delicious food on your palms to feed the dog. This feeding method is very safe, the dog will lick the food and will not bite the hand. After your dog gets used to it, you can tentatively hold the food bowl in your hand and feed it to your dog.

Next, you need to get your dog used to having someone around when eating. When you feed it, put your hands on it first. While petting it, pour food into its food bowl. Don't stop petting it while it's eating. The movements should be gentle and slow, and you can talk to it, so that it trusts that you will not steal its food.

Don’t rush into petting, and take your time depending on how well the dog accepts it. You can start by stroking the back half of its body, and then gradually move to the head when it does not object (this process sometimes takes several days to complete).

Once a dog adapts to having someone around and petting him while eating, he will not issue threats. Start trying to take away the food bowl. During the whole meal, if you find that it is threatening, such as starting to wrinkle its nose, making whirring noises, looking at people sideways, etc., scold it loudly; if it bites, you should hit it, but not too hard. You can use a newspaper to hit it. , and take away the food. When it calms down, praise it, pet it and say, "Very good." Then give it a food bowl. Keep doing this until it stops resisting.
