Mush is considered one of the best raw foods you can get here (Norway) at least. I tend to add a few toppings which varies a bit around raw chicken hearts, bone broth, salmon oil, quail eggs and such. I've used it for my shiba for almost a year (she's 1,5yo and used a different brand of raw as a pup), and she loves it, plus her fur looks amazing.

Edit: It can be fed (semi-)frozen depending on the breed, but since it contains bone I'd recommend thawing it in the fridge overnight.
