That's awesome. I do the same for my dog, saw some TEDtalks about cancer rates in dogs. I don't know how accurate that is, but it stuck with me. I started cooking a lot more for myself and got in a health kick, so cooking for both us at the same time is simple.
You might want to look into feeding her fresh veggies as well! I usually include some broccoli, caulliflower, and carrots in her meal.
Also be careful with canned meat, they're usually high in salt. You can rinse them off three minutes+ and reduce that salt content by 80% (for tuna at least, I imagine chicken wouldn't be too different).
Thanks for the tip about the salt. I'm trying to make it more freshly cooked chicken, rather than canned.
My dog chews weeds sometimes. I guess that's how she gets her veggies. I don't eat any veggies myself, so unless I eat it, she probably wouldn't either.
