When I first started feeding my dogs Innova.. they did not want to eat it! i would wet it so it could be a little bit more appealing, but to no avail.. I was going to give up.. but didn't!
They started eating it when they were hungry.. they won't starve themselves.. it just takes getting used to is all. If you are worried the bites are to big, you can also give the Innova EVO. That is what i've been feeding for a year and a few months now and wouldn't change it for anything else.
don't give up on Innova, it produces great results and you get the best bang for your buck.
