I've decided to start feeding Lexie half raw to see how she does on it. I just received my bag of Stella and Chewys dehydrated raw and I'm completely lost on how much to give her. Is 1 pattie a day too much?she's on Orijen Regional Red kibble and gets 1/3 cup a day should I cut that in half or even more than half. Oh and she's 6 months old 4.5lbs.
