To prevent your dog from mistaking dog food, there are several methods you can try: Assign separate food boxes and water fountains to your dog. This will prevent other animals from eating your dog’s food. Keep your dog's food out of reach of other animals. For example, it can be placed in an indoor space used by the dog alone, or placed in a place higher than the ground to prevent other animals from eating it. Keep your dog's surroundings tidy while he's eating. Dogs like to search around for food before eating, so you should make sure there is no other food around that your dog can eat.
Supervise your dog while he is eating. This will help prevent your dog from eating something that is not suitable for him. Train your dog not to eat other animals’ food. Dogs can be trained by giving them “no” commands or by giving them positive rewards. Hopefully these tips will help you stop misfeeding your dog with dog food.
