Does your dog invite him or herself onto your furniture ?
If the answer is yes, my follow up question is: why can't they have their own furniture? If the answer is no, my follow up question is: why not their own furniture? While our dogs want to be near us, they don't have to be sitting on top of us, so I recommend getting them their own bed for the room(s) that they most commonly relax in.
They can quickly learn that their bed is a target location which will make training them easier, too. You can teach them the command, "go to your bed", or "go lay down". Teaching your dog to calm themselves down and relax is one of the best things you can teach them.
Whenever I work with dogs who are especially "in people's faces", I can tell that they learned somewhere along the lines that it's very rewarding to be in people's faces. Solving this is not very hard, we just have to help the dog understand that it's more rewarding to not be in people's faces. Simply teaching a dog that it's rewarding to be calm and spatially respectful can be the difference between a well behaved dog or a poorly behaved dog.
Who owns the furniture in your household? Does your dog think that they own it and are they showing that to you by jumping on it (or you) whenever they please? This can be solved and your dog can learn that you have your own space and they can have their own space as well.
