Cow's milk isn't digestible to dogs at this age, so I would definitely not give that or you will almost certainly get loose stools. A boiled egg is high in calories also, so its best to limit this to 3-4 times a week at most or you have the potential to make Charlie a bit overweight. He is a rather cute puppy though. Enjoy the awesome puppy moments with him. Thanks for visiting Petco Pet Education Center, formerly Petcoach. Take care!
