The simplest way to train a dog to guard its food is to hit it. You can also use other methods to make the dog feel scared, such as screaming loudly, making vibrations, etc., as long as the dog is able to guard its food. It feels bad, as time goes by they won’t protect their food.

Tip:

It is natural for dogs to protect their food. We need to be more patient when making changes. The most important thing is to let them know that we will not snatch their food.
