The owner can use the starvation method for French Bulldogs. The operation method is as follows: eliminate any snacks and complementary foods, only feed the dog dog food at a fixed time, feed it twice a day, and do not eat the first feeding. Remove it, remove it without eating for the second time, and repeat the action the next day until the French Bulldog eats dog food. Later, when the French Bulldog does not eat dog food, you can continue this method. You can also take the dog for more walks to consume the dog's physical strength and increase the French Bulldog's appetite.
