Aw, I'm sorry the NV Instinct isn't working out for ya anymore.
Jackson still loves it and does well on it. I was considering buying a bag of the NV Prairie just to try it out since it's lower protein, but still the same brand, for these winter months coming where he's not as active. I got another e-mail coupon from them for a "buy one, get one bag free" so I might buy an Instinct and use the free one for Prairie and see if he likes it.
