Don't feed it! A recent batch had too much vitamin D in which caused kidney failure and several dogs have died. I don't know if it is in UK batches - the post below suggests USA from the language. " I need you to all do me a favor. This is my little fur baby, Duncan. I am sure most of you have seen my posts that Duncan recently died, and I found out two days ago that the cause was that his food, z/d dry and wet dog food, had too much vitamin D in it and caused renal failure. I have spoken to Hills twice. They explained that they were using a 3rd party supplier who did not adequately test their product. When I asked “what quality controls does your company have to ensure the products you receive from suppliers meet quality standards”. The response was “we are putting those into place now. Well, Hills Nutrition....it is too late for my little Duncan. This is inexcusable. Over the last 2 days there have now been over 4000 posts on the Hills Nutrition page of people indicating their dogs have died of the same symptoms over the past 90 days. Some cats as well. It doesn’t seem to matter if it is wet or dry dog food. Also, today alone I have received two phone calls from a neighbor and a friend indicating their dogs had the same symptoms and died and were using the same dog. My ask is this......if you love pets or someone you know does, please share this if you can. It may not have the share button, but you can cut and paste my message or do a screenshot and repost it on your page. Do not be fooled if you use Hills Nutrition Food if it is not on the recall list. They do not check their suppliers work and have no quality controls. They do NOT deserve to be in business. Also, a large corporate law firm in Chicago reached out to me two days ago and has started a class action suit. If you know of anyone impacted by this who is interested in joining it, have them contact me. To add insult to injury, during my conversation with Hills they offered me coupons off of new food in the event I get a new dog. This company needs to be put out of business. Switch immediately to another dog food like Royal Canine or make your own food. Kelly Bone"
