The breeder can mix meat into the dog food so that the dog will eat it together; if the dog only eats the meat, it is recommended that the breeder stop feeding the meat. Only feed the dog food and put it away when it is not eating. Feed it when the dog is hungry and put it away when it is not eating. If you keep doing this for a few days, the dog will eat when it is very hungry. You can repeat this twice until the dog is no longer picky and can eat dog food.
