I'm very happy to hear you've gone the route you have with your dogs. I work with animals on a near-daily basis, and when owners ask me what I believe is optimum to feed their pets, I receive varied responses when I respond 'raw'.
I just don't see how a diet of cooked, dry kibble fed from weaning-age 'til death is optimal - or even exciting. No wonder dogs beg for table scraps or dig in the trash!
Do you use any homeopathics with them, as well? If so, how do they respond?
