Recently I've had to change dog food due to the stores not being able to get any. I changed to Organix. They love it and I am finding I have less poop to pick up than ever. It works well with Rex's tummy too. The only thing is that it stinks like fish to me. Even Rex's breath smells a little like fish too, LOL. Not Coco's. I find that weird that I don't smell it on Coco's breath. But the food seems to be doing a good job with them. It is a little more pricey than the last one that I used to feed them, which is fine if it does it's job.
