Where to donate dog kennels and unopened dog food

I have two medium sized dog kennels and a bag of unopened dog food (accidentally bought grain-free which my picky dog won't eat) that I'd like to donate to a pet rescue organization. Does anyone know of organizations that want these items and will take them? I'm sure the SPCA will take them as a last resort, but I'd prefer to give them to groups that may have fewer resources/money and be more in need. TIA!
