Purina Pro Plan Shredded Blend Adult Dog Food Review

I decided after many not so good reviews from a number of people at the pet rescue I volunteer for and my vet that Hills Science Diet isn't a quality food for my dogs I made the desicion to swith to Purina.  I've heard great things about Purina so I figured I would give it a try.  While at the pet store I was looking at the Pro Plan with real Shredded Chicken in it.  I thought it would be nice since I currently give my dogs a dry and wet food mix and I would like to ween them off of wet food.  Anyways, after only two meals of mixing the Pro Plan with real Shredded Chicken with the food they are currently on, my Italian Greyhound started vomitting extremely mucusy yellow bile with chunks of chicken in it.  After only one meal my standard sized Greyhound began to deficate more than normal, have terrible gas, and burping an extreme amount.  DON'T FEED YOUR DOG THIS FOOD!  It just isn't worth it.
