Rhonda, I’m new to raw myself. What I see people do is to feed their dog in a space that’s easy to clean up, so a tiled area. You can feed your dog outside. You can provide a piece of linoleum for your dog to consume raw on it. You have to teach your dog to stay on it. Some put down a cloth, or you can use a drop cloth (plastic). It is a messy thing to feed raw. I’ve seen people feed their dogs in a large wire crate.
You can take a bone or meat away and refrigerate it for another day. I’ve never seen anyone address if they bury it.
Depending on the size of your dogs, some bones are more appropriate than others. People tend to feed bones that can be consumed. One that are hard are the ones that a dog can chip/break a tooth on, so many serve chicken. Where ever you feed your dog, you need to watch your dog consume the bone. They can choke. You have to be ready for that. I don’t see it mentioned on my raw site, but Capri got the keel bone of a chicken breast stuck in her mouth. I looked over and she was not moving. I removed it and gave her a few pressure compressions, because she looked like she wasn’t breathing, then she was okay. No one talks about that, so it’s something to be aware of and that they can choke.
I belong to a raw FB page called Raw Feeding. You can join and ask questions there. They have files on the page that they want you to read up on first, because they can answer questions (they’re articles). I’m still learning.
Something that they do that I didn’t learn right away is “trading up”. If your dog is at the end of their piece of meat or bone and you think they will gulp it, you offer them something they like better to get it away from them.
