Passover dog food

What basic standards do I need to follow for pet food for Pesach?

I’m mostly concerned about the ground wheat. That sounds like flour to me. Now if they add water, that can be chametz. The kernels themselves not ground would be a problem to eat, but you can keep in your house and you can feed to the pets.

So all certified grain free dog food is ok for passover?

Yes
