Hi Jens –
Check out the “Transitioning to Raw” thread and the “Suggested Raw Dog Food Menus?” thread – there are a lot of tips on getting started and some recipes there. Dogaware.com is a great resource for beginners and I would also recommend purchasing a copy of “Unlocking the Canine Ancestral Diet” by Steve Brown – it’s a very comprehensible and quick read, a great book for raw newbies. As for a grinder, I personally don’t use a grinder for my RMBs – your dogs miss out on the dental benefits if you grind the bones. I know a few people here do use grinders though, maybe one of them will pop in with what kind they have.
