I don't feed a lot of pre-made raw. I source all my meats at various locations, more work, but WAY cheaper than pre-made. In the winter I can get double ground whole carcass chicken 50lbs for $27 and double ground whole salmon 50lbs for $24 by going to the mushers. They get a huge discount on price because they buy bulk, so I just tack an order on through them.
In the summer, I do pre-made raw, grocery store anything on sale and kibble! The kibble I also buy from the mushers, who get the discounts on the bulk orders, so my kibble is $55 for 40lbs. And the food (while it may not work for all dogs because it is quite calorie dense and rich) has been totally good to my Shepherds and Poms.
