Thank you ALL for your valuable input! I'm already feeling better about using a multivitamin etc. Dr. W. originally had me using a tiny bit of iodized salt (for the iodine) and a little salt substitute (for postassium). I have a feeling that's what we'll go with. He did say that I could go with Nature Made for Her Multivitamin since that would be a more natural alternative if that's what I wanted to do. He's going to be very tired of hearing from me

, but I sent him another email saying that now that I've had time to process it, I think I'll be going with his diet (and returning the supplements my vet had me buy yesterday....hopefully they'll take them back!--I did ask him if the Canine Hepatic Support one was any good, though, and if he thinks it is, I may keep that one, but I'm guessing she's getting everything she needs without it.)
I still think I'd like to include some veggies (cooked or pureed--just for fiber and varitey), but that would really just be extra I guess. We'll see how this goes......not knowing enough combined with professionals who have a differing opinion, even though it's not a huge one, is really difficult! Thank goodness I get a lot more insight from all of you! That seems to help to clear things up for me a bit!
