My pup is a picky eater too... I was worried when she hardly eat at all.. and my breeder suggested to give her some baby food mix with a lil bit of finely chopped meat.. and she licked the bowl clean
! After a few days I feed her with the puppy food mix with a bit of the meat again.. I only give her a spoonfull of the dry food... sometimes she finish 'em off... sometimes she doesn't.. and when she doesn't eat at all, feed her by the spoon , or with your finger (with the baby food) and she'll lick it clean . hope it helps
