How often do you rotate between foods and how many foods do you rotate? I've noticed with Saga that by the time we reach about 30 pounds(which takes about a month and a half or so) of one food she starts to get sick of it and starts turning her nose up at it. She will eat it with gusto at the begining of the new food cycle to the point of licking her bowl clean. Well enough to make me think "Aha! I found the magic bullet!" Her food is only left down for about 15 minutes and she won't get it again until her next mealtime. Also, she self regulates the amount she eats, volumewise. She generally will only eat 2 1/2 cups a day, sometimes I can get her to eat 3 but more often than not she will leave that extra half cup in her bowl. She is on the Kirkland right now and she has lost a little bit of weight on it, so I was going to switch her anyways to something packed a bit more of a calorie punch. At least now I have narrowed down a pattern to her bitchiness. We have already tried Innova, both puppy and regualr green bag, Canidae ( which made her coat nasty), Kirkland and I am going to try her on Pinnacle next,because maybe there IS a magic bullet out there somewhere, won't know til I try right?
