How do i keep my dog from chewing and barking inside and outside?

Dogs have to chew on something.  Provide proper chew toys so it doesn't chew up your stuff.  Put your stuff UP where the dog can't get it.  Dog proof your home so you can provide a safe environment for the dog.

Dogs bark, that is the sound of a dog.  They don't meow, moo, nay, cackle, dogs bark.  You can stop excessive barking by googling 'stop excessive barking'.  But know what is excessive & what is not.

Train your dog to chew on chew toys. I'd recommend Kong toys as they are extremely durable. Go for a wobble toy as the treats inside can work as incentive and training. They are easily available on online pet stores like Petcarerx.

Training and supervision.

You have anxious dogs! Dogs know that chewing releives anxiety so seek out anything they can chew...you get upset, shout/moan and that makes them more anxious, so they chew more, anxious dogs are fearful of all/anything so you shut them outside and the bark as they are anxious, alone and have undeleted energy that is not being used............ and if you are prepared to change YOUR behaviour your dogs will change theirs................ so it all depends on you and what positive behaviour changes you are prepared for...like more lead walking daily, more socialisation ( new smells, sounds, sights) daily, providing positive chewing like raw bones and raw carrots and teaching your dog more tricks, as anything you teach from 'sit', shake hands, 'find it' to 'leave it' builds their confidence as well as their obedience

Most dogs need more AEROBIC exercise, not just a walk.  In addition, high energy dogs are also highly intelligent and need a job, or need mental activities/exercise in order to use the brains they have, in positive ways - or they will "FIND something to do" - often things you will not like.  

Herding breeds often benefit from actually getting into herding or agility classes - for example.  Sporting dogs can be taken to run loose, on large fields, even if there are no hunting birds.  Take a canvas dummy or tennis ball launcher & get them running and retrieving.  If they have a protective coat - they can also do WATER retrieving, even in winter.  Put a doggie back pack on the dog, and let it carry some weight (for an extra exercise workout) - like water bottles for BOTH of you, and poop bags. look into lure coursing (again done totally outside) and appeal to any number of breeds if they have ANY "chase instincts".  And yes, on rainy days give the dog a food puzzle toy to FIGURE OUT.

If the dog can see outside - to bark, it might be more likely, so close the blinds/curtains or leave dog in an area, where it DOES NOT SEE OUT the window.   Same is true for outside.  Dogs bark a lot due to being protective OR due to boredom (which boomerangs back to all the exercise & mental stimulation - you need to provide) and being able to SEE OUT, if you do not choose to have a solid fence.  I do NOT leave my dogs outside, so I can PREVENT bothering my neighbors (two of which are nurses) - who work varying SHIFTS and may be sleeping during the day.  When dogs get enough exercise and daily mental stimulation - they can be safely left indoors.

It starts when they are puppies and after that it is an engrained behavior. My dog is a watchdog but also a member of the family. When someone comes down our driveway he will immediately start barking. Dog's are territorial but where humans are concerned that territorial nature goes hand in hand with loyalty and it is up to them to keep their master safe and to let them know when there may be a threat within their territory.

That basically means you are trying to get a 6 year old to stop talking to their parents, so good luck with that. When he is inside he will only bark if there is a sound he doesn't like and more often than not there is someone or something(rural life) outside which he is unsure about. As such I will not tell my dog to be quiet because I raised him, after he came in as a stray, to be himself but would also chastise him for barking at neighbors which he eventually learned is NOT his territory.

How? With discipline but it needs to be with the dog's interests and instincts in mind. Simply telling the dog to shut up because it bothers you or others doesn't make any sense to the dog so you would confuse him and stress the dog out. Think like the dog and train him without selfish motives. 

The same applies with chewing. If the human doesn't pay attention to the dog enough or provide them with the appropriate chew toys/ raw beef bones they will do what we do and bite on other things like pens, our nails or pencils. It's a nervous habit born of neglect. My dog seriously always has at least one ball and a chew toy bone available to him and then there's the playtime with tug of war, fetch, hide and seek etc.. How in the heck do you play hide and go seek with a frigging dog? Not hard, I throw the ball and run away and hide. 

It's usually neglect or the breed of dog that results in apparent misbehavior. That means you could get better info if you told us the breed of the dog.
