[Q]: I have been giving these chews to my Mini-Pincher and Mini-Dauchand for the past 3 years to help support their joints and hips.  The last batch I bought is darker in color to the point of almost being burnt and smells a lot more.  It made my Mini-Pincher sick to the point of vomiting and liquid stools.  I am going to shop for a better product that is made here in the US . . . I have been looking at GNC products for Dogs and that is probably the route I will take.
[A]: Negative


[Q]: I adopted my dog about 6 months ago and he had digestive problems that the vet could find no cause for. He would get diarrhea with mucous in stools regularly. His stools would vary from constipated to unformed soft stool. I decided to switch him to a better quality food and did a lot of research. Newman's Own had all the qualities I was looking for, so I switched him to it gradually - 1/2 Purina One and 1/2 Newman's Own at first and gradually more Newmans' Own in the mix until finally 100% N.O. Ever since switching about six weeks ago, he has not had constipation or loose stools. I also don't hear his tummy roiling after meals like before. And despite what a few reviewers have written, the chicken and beef used in the pet food, while not "organic", is "natural" and raised without hormones and antibiotics.  According to [...] ingredients list: "Natural Chicken - Raised without growth hormones and antibiotics and fed only a 100% natural, all-vegetable diet, the chicken meat provides amino acids essential for muscles, hormones, enzymes, antibodies and structural and protective tissues." Also, the beef is free-range anad range fed w/ no hormones & antibiotics.  For me the evidence is clear - this is good quality food, my dog loves it and I love that when I buy Newman's Own products, the royalties go to charity!
[A]: Positive
