If you want to train your dog on food yourself, there are a few points to consider: First, make sure you know your dog's dietary needs. Your dog's dietary needs depend on his age, size, activity level and health. Some common nutrients include protein, fat, carbohydrates, fiber, minerals, and vitamins.
Plan your recipes. Choose appropriate ingredients based on your dog’s dietary needs. Some common ingredients include chicken, beef, lamb, duck, fish, beans and vegetables. Note that there are also some foods that dogs cannot eat, such as chocolate, grapes, pears, garlic and onions. Use appropriate cooking methods. Dogs' digestive systems are different from humans, so they cannot eat raw food. It is recommended to cook the ingredients until soft and mushy, and then mix them with appropriate dietary proportions. Store food in the refrigerator or freezer. This ensures the freshness and quality of the food. Observe your dog's health regularly and consult your veterinarian promptly if you have any questions.
