I lost my galgo, Cruz, to kidney failure on 10/29/12, so I know what you're going thorugh. He was on Mirtazapine to stimulate his appetite (worked well) and Carafate helped to coat his digestive tract. He absolutely would not eat the kidney diet foods and quit eating any commercial dog food the last few months. At that point I gave him whatever he wanted to keep him eating. I'm sorry you're going through this.
