For a time my dogs were getting brown organic rice and it was noted that they seemed to have a harder time with defecating. I read/heard somewhere that you should not feed brown rice...It should only be white. All that changed for us as I was tired of making their food.
After much research, there are many good choices of dog foods out there. You just need to find the right one.
I find that Wellness and Merrick work well for my dogs.
I have been through it all. I want to give a

to WHOLE DOG JOURNAL publication. It's is a great 5 page of valuable information every month.
