I know this is frustrating!
Did you mention that you recently moved? If so, he's probably hearing sounds that are different for his surroundings. He is being territorial & he can't rest either. Poor Guy! & Mommy!
My daughter's dog has anxiety with the barking/noises, etc. But no problems sleeping @night. I have heard/seen pills for anxiety for our furbabies. Maybe someone else can post if they've tried it or ask your Vet what they would recommend. It sounds like anxiety to me. I wish you Luck/much needed Rest!!
