My old dog was allergic to corn and wheat and broke out in hives and even cysts when she got into 'people food' or if someone gave her a dog treat that wasn't lamb and rice based.

My current dog eats a commercial dog food made of potato, herring, and brown rice with glucosamine and chondroitin. I've only had her home from the shelter for a month now and she seems to be improving in health by the looks of her coat. I'm a big fan of oily fish as a dog food. I give her egg and mackerel for treats sometimes.

Humboldt, as far as checking out the poops, indeed they seem to vanish after a good rain or the first day above freezing when the snow is melting. I don't have 'lawn mine' problems from indigestible fillers.
