I don't really give my dog many grains, so I would not have thought of that. I do keep a few jars of some meat and veggies mixtures. I had originally gotten them when Haley had a molar pulled, and I was afraid she wouldn't be able to eat regular food. Wrong!
I basically feed her lean meat and vegetables for dinner anyhow, so I sometimes mix in the baby food. It was really difficult, though, trying to find flavors without things such as salt and Sugar added.
