I had fed Nutro natural choice for over 10 years with no issues. In April 2008, my malamute and mal/shep mix, who had never had any health issues, both became critically ill within the same weekend. They had fevers of 105, and their liver/pancreatic levels were off the charts. The vets at the emergency clinic were stumped, only said the symptoms were consistant with poisoning. (They had absolutely no access to any poisons). My vet bills were over $2000. My 12-yr old girl died 2 days later, My 9-yr old recovered when I began cooking his own food, but has a permanant head-tilt from the neurological damage he suffered.
If you go to consumer affairs.com, there are dozens of similar stories, most taking place between March and July of this year. Nutro is denying any involvement whatsoever. Every time new evidence is released, (including recent proof of zinc/copper toxicity) they refute the evidence and issue a statement stating how safe their food is. I've talked to their customer service reps on multiple occasions. They read canned statements and lie to me about looking into my case. They want all the information I have sent to their legal department, and offer no other recourse.
Earlier in the year you could not find Nutro lamb and rice on the shelves. Nutro stated it was a 'supplier issue'. That is a lie. This was the same time as the poisonings.
More and more information will hopefully continue to come out. I believe this case will be as big as the 2007 case. Please don't feed your dog Nutro! Even if it's not every bag, it's just not worth the risk!
