Why is my dog's head shaking uncontrollably? Should I worry?

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.

Unfortunately, that's hard to say what the cause is without being able to conduct a neurological exam. It could be indicative a permanent nerve damage, pain in the neck or a congenital condition. I recommend to record the behavior on video and then ask the neurologist to view the video. The neurologist is the best person to accurately answer your questions about Dodger. I'm glad he's doing well and please feel free to post any additional questions.

This sounds like possible partial/focal seizures. I suggest you take her to your vet for an exam. Show them the video since she isn't likely to be doing the behavior during the exam. veterinarypartner.vin.com/default.aspx?pid=19239&id=4951440

This sounds like a neurological problem. It can be from and injury, epilepsy or an infection. You can put a video on YouTube and resend this question with the link. Also more of a description. Tell us if you are seeing this all the time or only certain times of the day. Your dog’s age and breed may help also. If this head shaking worsens then please take her in for an exam.

You should have Lucky examined by a vet. Any abnormal behavior should be taken seriously. Since I can't see what he is doing it is hard to comment on why he is doing this behavior. It could be a type of seizure activity. It is best for him to be checked out by your vet in person.

I am sorry there is no video attached to this link. I would recommend taking Monty to the vet and showing them the videos. in some breeds like bull dogs they do get idiopathic head tremors (we are not sure why head tremors) that are non harmful and do not have a treatment. However in other breeds it could be a focal seizure and needs more attention. A vet visit would be the best place to start. I hope that helps

Head shaking doesn't indicate anything on its own. It could be that there is something irritating Orvia's ear or nose, itchy skin, a bug bite causing a reaction, neurologic or muscular issues, or more. If you are seeing other signs and symptoms in addition to the head shaking (loss of balance, nausea, confusion, etc), discharge from the ears or nose, or the head shaking doesn't resolve, having a vet take a look in person is best.
