Why is my dog's head shaking uncontrollably and preventing sleep?
Oh my. Poor guy. This sounds like muscle tremors and is a sign of a severe neurological abnormality that can be caused by a toxin ingestion, underlying brain/spinal cord tumor, or even an underlying metabolic imbalance (not as common). I would highly recommend taking KyCzar in to your vet to have him evaluated. Baseline bloodwork will likely be recommended and perhaps even a referral to a neurologist, if you wish to pursue further treatment and work-up.
Unfortuantely there is not a good way to share videos using the free posting to the forum service. You will likely need to open up a private chat with an expert in order to share a video of your pet. But from the description, this sounds like potential muscle tremors or a neurological disorder for sure.
I do hope that your fur baby is able to make a full and speedy recovery. Best wishes and take care.
