I decided to try a grain free food for Ida, just to see if it makes a difference with her. I went to Pet Club, intending to get her Nature's Variety Instict Salmon, and ended up with Natural Balance Fish and Sweet Potato. It's grain free but also is limited ingredients for dogs with allergies. She really seems to like it, and so far it's been no problem just giving it to Ida. She eats her food, Clementine and Gertie eat theirs'. I'll take Ida back to the see Dr. Anderson tomorrow and try to make a decision on her surgery, or pin him down better on her eye issues. I figure in the meantime, she can try the grain free food a while and see how that goes. If it turns out to not be allergies, she can switch back.
