Have you tried adding a little warm water to the kibble? Your pup may prefer soft food, I would try a can version of the same Science Diet food you are feeding now and see if that makes a difference.
Next time you take him to the vet make sure they take a good look at his teeth.
Small breeds tend to have lousy teeth. Maybe he needs a dental cleaning.
Just saying to rule out issues that may cause him discomfort when he eats hard food.
