This could be due to some type of anxiety. if anything has changed in the house - new routine, new pets/people, loss of pets/people, new construction, less exercise, etc, this could be the cause. Sometimes they will also develop separation anxiety from you which can cause these behaviors. If he is friendly with other dogs and social, you may try taking him to a doggy daycare to see if this will help get some of his energy out. You can also try to add a calming collar like adaptil. If this doesn't help, you can talk to your vet about starting him on an anti-anxiety medicine like fluoxetine or something similar to see if this helps to calm him down. I hope this helps!
