First, I have to ask. Is anyone else not getting the email notifications?? I have to go back and find posts to even answer. I would look for a food that does not have any corn in it. Look for a food that has meat or fish as the main ingredient. A lot of people have good luck nutro natural choice, or nutro ultra. That one is a holistic food, and seems to be good. Not sure if you have a costco by you, but people also feed their doodles kirkland chicken and rice, or lamb and rice. It is a good quality food for a lower price. Also, remeber that the first few days, Belle won't know which door to use to go potty, so you will have to show her the door you want her to use. Best of luck to you and Belle, and let us know how it all goes.
