I used it for a little while just recently. Prior to that I was using Pedigree, and my dogs were loosing large amounts of weight. I was going to switch to PMI nutrition, which the feed store was selling a lot of to local houndsmen, but they were out at the moment, and the truck broke down. The Pro Plan is more expensive than the PMI, but they sold it to me at the price of the PMI because they told me it would be in, but it wasn't. Anyway, that was about a month ago. I weaned my dogs off of the Pedigree, and they seemed to gain some weight which was a good sign. There was also less waste than with the Pedigree. This last time I went to Elko, they had the PMI in, so I bought two bags of that, and am working on weaning them completely over. So far this stuff seems to be good too, and the dogs are eating a lot less, and maintaining their weight a lot better.
