My 8 month old Cav is a problem eater. We have tried all types of food and he just turns his nose up and walks away. I have to literally hand feed him his food. He will take bites of his dry food but not much. What do I do? He weighs about 9lbs and is a very happy little boy. We have to board him for a week at the end of the month and I am scared to death about him not eating!
