In terms of diet, besides feeding at fixed times, fixed amounts, and fixed locations, you can additionally provide the dog with specific stimuli to enhance its appetite.

　　For example, before adding food each time, you can ring a bell or call the dog's name twice first. Persisting with this will help your dog form a meal preparation process, stimulating its digestive system into an excited state and increasing saliva secretion. This way, eating will go smoothly, and the dog will eat the fixed amount every time.

　　Before your dog starts eating, you can slightly control it, because at this moment it is very hungry and eager to follow your instructions. For example, you can place the small mixing tool for dog food aside, and each time have it fetch and hand it to you. This habit is easy to cultivate because at this moment, the dog appears especially attentive.

　　You can also have the dog start eating based on a command. Before the command is given, the dog will look eagerly at the food bowl, eyes revealing anticipation. This controlled waiting time should be kept as short as possible; otherwise, it may negatively affect its appetite. This practice also helps the dog develop the habit of not snatching or stealing food. Whenever someone offers it food, it will consciously raise its head to seek permission from the owner.

　　Some dogs have very poor eating manners and often make a mess. At this time, you should slowly train them to understand rules, making sure they lick their dishes clean and do not waste food.

　　You need to train the dog not to pick up food on the ground and not to eat food given by strangers to prevent accidents.

　　Choose a calm environment, place food the dog likes in a visible location beforehand, then bring the dog there to wander around and gradually approach the food location. When the dog shows interest in eating, immediately issue a "No" command in a threatening tone, accompanied by a strong pull on the leash to stop it. When the dog stops scavenging, give a reward, then continue the training several times.

　　If you can stop the dog's bad behavior at a close distance, then use a training leash to conduct long-distance training until even without the leash, the dog obeys commands and hand signals to stop scavenging.

　　In daily life, you should also cultivate the dog's good hygiene habit of not picking up food from the ground. The refusal training method: In the training area, have a stranger naturally approach the dog and offer food. When the dog tries to eat, the owner gently pats the dog's mouth while issuing the "No" command. Then the stranger offers food again. If the dog still tries to eat, apply stronger stimulus until the dog automatically refuses to eat. You can also have someone throw food in front of the dog, and when the dog tries to grab or pick up the food, the owner immediately issues the "No" command and pulls the leash strongly to stimulate it. If the dog can refrain from scavenging on command, it should be rewarded. (Source: PetsZone)
