I was feeding sportmix before the prce went up and the amount went down then i switched to retriever blue bag from TSC. ONly problem with both was i had to feed the heck outta my mutts to keep weight on them. Switched to red bag ol roy for my inside dogs and the did so well that now all the dogs get it. 20 bucks for a 50lbs sack and i dont have to feed as much of it.
I rotate back and forth between the retriever and ol roy...seems at least once a year the dogs get used to the feed then I have to start feeding more of it..then when I switch they are back fine again.
