Three major points of dog eating habits training:

1. Meal time training. The time for your dog to eat must be limited, generally 10-20 minutes is enough. Many owners let their dogs eat for a very long time, which is actually a very bad habit. Generally, dogs will be taken away after eating for more than 20 minutes.

2. Don’t give your dog too many snacks. When your dog eats, try to focus on dog food. Do not add some food or canned meat at will, especially don’t add canned meat every time. This will easily damage the dog's mouth, and it will easily stop eating dog food in the future because there is no added food.

3. Be persistent and don’t be soft-hearted. Because dogs are very smart and know that as long as they tolerate it and don't eat dog food for one or two meals, the owner will feel distressed and offer more delicious food with both hands. It is recommended that owners do not do this, as this will make your dog more emboldened and picky about food.

Methods to train dogs’ eating habits:

2. Induction: Induction refers to a method of inducing a dog to perform a certain action by using delicious food and the trainer's actions.

3. Punishment: Punishment is a method used to prevent the dog from abnormal behavior due to incorrect movements, including reprimands, tapping on the head and neck, etc.

4. Force: Force refers to the use of mechanical stimulation and threatening commands to force the dog to perform corresponding actions accurately and smoothly.
