I use to feed Eagle Pack Holistics, but all of a sudden all my dogs refused to eat it. Currently I am feeding ProPlan, and I read a few of you don't recommend it, but my dogs are actually doing very well on it, and so far this litter is doing awesome too. I was thinking about Nutro, I try to switch my dogs food every 6 months or so for a little variety, so I may try Nutro at some point. I have a friend who has her Golden on the Nutro Ultra, and she's pleased with the results so far.
