I haven't been on this board in a while but my dog Jake is dealing with this right now.  EVERYTHING I have read and heard says to drop kibble completely.  We have been using canned food and adding water to that for him.  With his size, it is costly.  I am looking at using Honest Kitchen but figuring out which version to feed.  I'd like to get a consult from Sabine soon so we can homecook for him too.
