Wow, thanks for the link. I just got a new puppy 2 weeks ago and the day before I picked him up, I went to my local pet shop to buy some supplies. I was all set to buy Iams puppy food, but the sales rep from Wellness was there and she talked me into buying their puppy food instead, based on the type of issues that are raised on that website.
It's fairly expensive, but there are no by-products and no corn.
Congratulations on the new puppy! And, on heeding the advice of the Wellness representative!
Four years ago, I rescued a young basset hound to keep my other one company (hey, they're pack animals). Moses arrived with some grocery store dog food that I replaced with Nutro, a product I thought was much healthier. He also arrived with an ear infection and the vet put him on medication. Over the next 12 months, the ear infection would clear up and return. The vet kept switching medications. Finally, he suggested that we run allergy tests. Before we did, I came across the above link, read it through and switched both dogs from Nutro to Wellness. Over the next few weeks, I watched these dogs coats transform from dull to glossy. At his next vet check, Moses' ears were both clean as a whistle, and have been ever since.
Bottom line, you will pay more for a quality dog or cat food but you will be spared veterinary bills associated with the ailments and illnesses resulting from the cheaper food. You made a wise decision! BTW - Wellness has a frequent buyer program that will save you money over the course of time.
Merry Christmas!
