I have been feeding my little guys 3 0r 4lbs(the dogs weigh, not the kibble!) each organic kibble for awhile and am now swithcing over to/adding raw to that. i learned that, dogs aren't meant to eat cooked meat. the beef they get is lean and yes raw. you can find all kinds of info on the web. you can buy raw or just make/use your own.
some dogs or cats can swithch right over, others, have to go a little at a time. Already i see an improvement in coat and breath. I am really amazed!
Although when my dogs were sick and before i had heard of raw, i always used equal parts of lean ground beef and rice and some garlic (good for fleas and ticks) to make my own dog food.
I sure hope your little one is feeling better!!
