There is a supplemement called DINOVITE that you can sprinkle on their food, contains some natural vitamins as well as Human Grade Diatomaceous Earth -- DE cleans them out so they don't get worms and don't need working... There is some great lists on yahoo for people working through the process... k9nutrition as well as k9kitchen are both excellent.
Definitely I’ll check all that out. Do you mind if I FReepmail you if I need a little direction?
It is easy to feed raw. And once you get the hang of it you can make large batches and freeze it.
Diatomaceous Earth with garlic, etc. is a popular form of fly control for horses. I wonder if it helps control fleas and ticks on dogs?
