My Yorkie was eating Nutro for a long time. She was fine for a while but then I noticed her stomach was constantly bloated like she was going to explode. She vomited a few times, periodically. She also (as in the article) began having frequent accidents.
She is 5 years old and I knew something was not right and you can tell that she was not acting like herself.
Can't say it was the food but it shure as ever is a coincidence.
I have since switched her back to the brand I gave her before and she seems much better.
I've also read that dog food should not contain wheat, soy, corn and sunflower because it triggers allergies in dogs.
