Trial and error is how I learn about their health needs, as far as food is concerned, so I hear ya!
It's better for your dog's digestion to eat dry...as well as for her teeth. (If your dog were another type of breed I may not feel the same way about eating dry dog food...).
After 6 months try giving her whole carrots, (the long ones). Her tummy should be mature enough to handle it and she'll have fun chewing and eating. It's good for her and she enjoy massaging her gums...lol. (Watch out for her stool, if it's soft don't give it anymore. Start with her first piece about finger long...always keep an eye on her tummy by what her stool is doing). Food for thought...lol.
Also, you might want to give her a half a tea spoon of "Keffer" or yogert a day...to begin w/. It's awesome calcium...for a growing puppy. Up the dose each day...(keeping an eye on her stool at all times).
No matter how holistic the dog food..it's still bagged food which isn't as fortified and healthy as adding a little something-something to her diet each day.
