Hello, my name is Andrew an I have a toy yorkie that is 15 weeks old and he won't eat his food unless I feed it to him him one at a time with my hand. He was eating iams smart puppy until he was 13 weeks and I switched him too kibbled and bits an he ate it for awhile now he won't eat it, I'm not sure if it's the food or what. Please help I can't always feed him by hand and I don't want him to starve to death.
