You probably gave them too much liver, it makes their poop pretty tarry. I give mine a small chunk of it for the nutrients but 1 cup is definitely too much for my bullies. I'm sorry your hubby is not working with you Sherry, that has to be hard. Mine completely supports it as we have less vet issues than with kibble but it's easier for me as I just give them the food and they go to town on it, I don't grind anything. I hope if gets better for you.
