I highly recommend making your dogs food... it's a little more time consuming but at least you will know what's going in there. Plus, you can experiment a little more - I was always very generous with the meat and pasta vs. the eggs. Daisy would get so excited when she saw me grabbing the container from the fridge! Good luck to you and your dog!
Cant seem to open it either.
I do have suggestions. Go to Yahoo pet groups and look for K9Kidney Diet and join
or better, go to www.dogaware.com, look under health, and then renal or kidney disease. Lots of good solid info there. Also look in links, I think there's a link the yahoo group K9KidneyDiet and also K9Kidney group. Both are excellent and have reams of files covering diet, recipes for home cooked diets, meds, resources and so forth.
