I wonder if these spent grain treats are really good for dogs.
I think the dog food industry would tell us it is fine since their products are mostly comprised of cereal grains too. Probably many vets would say the same.
My dogs love Milk Bone treats, so I'm sure they'd love spent-grain cookies too.
But still... Dogs are carnivores by nature, not herbivores or omnivores. I've recently been feeding raw beef and chicken to my dogs. They go nuts over it. And then afterwards they want a Milk Bone... go figure.
