Teaching a puppy to get in the car and prepare dog food requires patience and consistent training. Here are some suggested steps you can try: Start by giving your puppy some treats. This can help the puppy better recognize that he is doing a good job and become more confident and motivated to learn new skills. Let the puppy see you take out the dog food and tell the puppy "dog food". This way the puppy will know that dog food is related to getting in the car. Place dog food in your puppy's food bowl. After letting the puppy finish the dog food, put the food bowl in the car before driving. Give your puppy some commands to follow you to the car. You can use the command "Get in" or "Follow me" to get your puppy's attention. After your puppy gets in the car, give him a treat. This can help the puppy realize that he is doing a good job and become more confident and motivated to learn new skills. Repeat this process until the puppy has learned the skill of getting in the car and preparing dog food.
Note: During the training process, be patient and do not put pressure or intimidate the puppy . Puppies need time to learn new skills and need your support and encouragement.
