The answer to this question depends on what the problems are. In other words, does the behavior make sense to you. He is cornered and combat is his only viable natural response. However, if you feed your dog every day, then one day give him a bone to chew and he bites you when you try to take it away, this is abnormal behavior for a domestic dog raised by humans. This behavior requires treatment from a qualified Animal Behavior Professional.
Many dog problems are management problems.
These problems can be solved with obedience training. A Dog Trainer or dog obedience instructor may be qualified to train this dog. You should look for a trainer that has graduated from training schools or internship programs. I also feel that a trainer or instructor should at least have a BA or BS in psychology, biology or some similar field of study. In the absence of obedience training, a dog who jumps, chews, barks and is generally dominant is simply being a dog, doing the things he would do to survive in the wild.
