Hi Danny. Can't talk much at the moment but here are some tips on how to start with raw:
Although a freezer is recommended, I have heard that it's very possible to succeed without one. I'm guessing that you're going to just need to go to the store more often, maybe at least once every couple of weeks. The only meat that I buy on sale regularly and in bulk are chicken and goat. The others rarely go down in price so you wouldn't need to store a lot of them all the time. I would encourage you to find a local rawfeeding group, that way you can exchange contacts and other info ie. who and where the best sources are.
I've also read that some rawfeeders manage to train their dogs to eat on a large towel for easy cleanup. If they step off the towel, then their food gets taken away from them for a bit, then given back again once they step back on. With any training, repetition is key. My boys eat inside an x-pen where the flooring is vinyl cleanup is simply a spray of a cleaner and a wipe.
