well there is nothing wrong with feeding your pup people food but i think 3 months is a bit young.. unless someone on here can suggest how to feed a young pup home cooked food. but i think he WILL eat when he gets hungry... but there is nothing wrong with apples.... carrots.... pears.... for a snack every once and a while... or even as a treat every day.. it is a GREAT HEALTHY treat!!! and you will at least know he is eating something
