I am sorry to hear that Abigail is not doing so well. I did a Yorkie  Talk search for Renal Failure food recipes on YT and came up with these answers. My prayers go out to Abigail and to you. Any easy way to search on YT is look at the bottom of any thread page and you will see a Goggle search box if you click the YorkieTalk.com button instead of the web button it will search only through postings on Yorkie Talk.
