The calcium carbonate is just a replacer for bone. If you were to give your pup a chicken neck with some meat or 1/2 chicken breast on the breast bone, a tiny bit of organs, add juiced blueberries, cranberries and parsley, you'd get the same thing. I think it would be much less expensive if you just did it yourself. If you choose to feed a small portion of veggies, at least you can add variety. You can also feed eggs with the eggshell for calcium. I don't understand the need for milk in a dogs diet
. We do feed the odd bit of cheese but that's more for treats than a mainstay of our dogs' diet.
Would you feel comfortable enough to not use the Urban Wolf?
