I am feeding Herkie a Canidae/Nutro mix....I was switching from Nutro to Canidae, but when I got to 1 can Canidae/1 can Nutro...he just seems to be doing so well on that, that I haven't completed his change. Usually he poops 1 time in the am, 1 time in the pm...and every once in awhile will poop in the afternoon.
But possibly, something in Canidae may not agree with him, and a gradual change to another kibble may be in order. You have to remember, every food doesn't agree with every dog. Sometimes you have to play around with different kibbles in order to find just the right one. Good Luck.
