To train a dog to enjoy a chew toy, have your dog watch another dog have fun with it.
If you have the right kind of chew-toy, some dogs also really enjoy a good tug-of-war.
Also: IMHO it's a good idea to give your dog a "sanctuary": someplace they can go where they know they won't be disturbed, and someplace they can retreat to if they know they did something wrong. My parents typically use a decent-sized dog travelling crate, depending on the size of the dog. Once you establish one, it's important to not disturb them while they're in it outside of dire circumstances.
I have three dogs. An elderly developmentally delayed dog (he wasn't too swift when I adopted him, but his seizures really fried some of his brain cells, thankfully they are now medically under control), a middle aged dog we rescued to help with the first dog (he was ball obsessed and didn't know how to find the back door when he was let out. He would stay in the back yard barking neurotically until we went out and caught him) which worked perfectly. He showed the older dog how to find the door, and broke his singular ball obsession. We rescued the third dog a few months ago, to play with the middle aged dog, because the older dog is too old to play with him. The first was not smart enough to train except for basics (sit, stay, out etc), the middle aged dog belongs to my son, and although he is pretty well behaved (we don't let dogs on furniture or certain rooms of the house), he is overly protective of the house.. The third rescue's training is coming along very well. He has nailed sit, down, heel, leave it and drop it. Yes, I recommend they all have their own separate 'time out' area where they can go to be left alone, or if they have done something they shouldn't have. My grandkids know to leave them alone when they go to their 'spots', and they all love the kids (although they are always supervised around the children). I am totally a dog person. :)
