GSDmommy, is his brother picky too? From what you’ve said, it sounds to me like he is just a picky eater. Our pit bull is like that. It was a lot of trial and error to see what he liked. I’d buy smaller bags and rotate frequently. It sounds like he may like fish and chicken foods so far. You are going to be pretty limited if you don’t want to order online. Have you tried Wellness Core Puppy yet? That should be available locally.
My Dane used to get bored when he was eating kibble and I had to change his food after every bag. He would only eat poultry based foods (chicken, turkey, duck…). It was a pain in the butt. I added canned food and The Honest Kitchen as toppers so he would get other protein sources mixed in. I thought he was pretty picky. About 4 months ago I switched him completely over to The Honest Kitchen and raw. He is not picky anymore. He eats everything now: beef, pork, lamb, chicken, duck, goose, salmon, whitefish. So far I have not found anything he won’t eat except for THK Thrive (I don’t think he likes the quinoa in it).
I’m sure that was not too terribly helpful for you but that is my experience with 2 “picky” dogs. I hope you figure it out. Good luck 🙂
