Nutrena River Run 24/20

i fed the river run for years (like 10 or so years) to my duck dogs. Did great untill I got into Hog hunting.Nothing strains a dog quite like hogs. I found that river run was unacdeptable for a dog under high stress the dogs were wore out after 2 hours of light hunting in the cool weather. I switched to black gold and noticed a huge difference in their stamina and stool. My dealer tried to sale me loyal but they wanted $33.00 per bag for a 40lb bag. and I cant afford that. I do know of a guy near here that supposedly runs a test center for dog foods and he said loyal is the best but it would cost me $5.00 per bag more than black gold and id only get #40. I did like the price tag on that river run though. I can get that white bag of 21% for about $20.00.
