I've used both Dr. Harvey's and The Honest Kitchen bases and both are good. My complaint about Dr Harvey was the amount of dust the mix kicked up and that it coated everything around my work area. When I asked the company about it they said that was normal and basically to deal with it so I switched to The Honest Kitchen. For Tessa, my 15+ year kidney dog, I use one of the grain free bases and mix it 50/50 with their Turkey Recipe which is what I feed to Josie. A few weeks after starting to do that, along with SP Renal Support, Naraquin, and Visbiome probiotic, her kidney values were back within the normal range. She loves the food and the supplements don't turn her away.
