When I got my dog I did a lot of research regarding dog food and dog food ingredients. There are high quality dog foods like this one out there, but you probably won't find them in regular supermarkets. While this food may be more expensive than other dog foods, it is well worth it. Innova Evo is one of the foods that were NOT affected by the recall. Also, the ingredients are healthier, and don't have high wheat/grain content or nasty additives. My Doberman used to have a lot of dandruff and had some skin problems. Also her poop was really mushy, almost diarrhea. When I finally switched her to Innova Evo Red Meat I'd wished I'd done it sooner. She doesn't need to eat quite as much, and her coat is beautiful! No more dandruff problems and her skin is great.

We have a tiny little 8 lb maltese, and we got him the mini size bag of these. Each time we give it to him, he seems to love it, but he had HORRIBLE diarrhea that led to multiple vet visits (it was awful, pretty much the worse diarrhea he's ever had at age 3). I noticed about 8 hours after he ate the nutrident, the diarrhea started and it had turned blackish green. Fast forward 2 months, and our dog was nursed back to health and happy...I didn't think that the nutrident was the cause of the diarrhea earlier, I thought it just made it worse so I gave him another one. Wrong. About 6-8 hours after, I noticed his normally firm stools were extremely soft and once again, they were blackish green. I promptly threw the entire bag in the trash. Terrible product and I will never be buying these again. As a side note, my little guy tolerates and loves Greenies just fine. I'll pay the extra few bucks for the Greenies to make sure he isn't food poisoned by these ever again.

I bought this machine 1 1/2 years ago, have trouble with it filling the cup and thought, OK, I might try it again, but after reading a number of reviews and the machine is still having the same problem, I will not purchase another Kurig.
