What is Jerking His Head?

You may notice your dog jerking their head every once in a while. When the behavior becomes more pronounced or occurs more often, you should have your dog checked out by your veterinarian. Sometimes your dog is jerking his head because he is startled or he is hand shy and fearful. In other cases, your dog could be suffering from a seizure, neck problems or even vision problems. 

When you first notice your dog jerking their head, take note of what was happening just before the jerking began. You need to write down everything you have observed including what activity your dog was engaged in, if there were any environmental changes and if there were any strangers, small children or other animals near. Your veterinarian will need this information when they examine your dog.

Possible causes of your dog jerking his head include:

  • Neurological disorders
  • Muscle contraction disease
  • Fear
  • Toothache
  • Vision problems
  • Neck problems

Why Jerking His Head Occurs in Dogs

Neurological Disorders

If your dog is diagnosed with a neurological disorder most likely it will be seizures when they jerk their head. Seizures are involuntary and will have either increased or decreased muscle activity including jerking their head. After your dog’s seizure, they will be disoriented and confused. They may also have problems with their vision for a time. 

Muscle Contraction Disease

This is a rare seizure disorder that is characterized by sudden jerking motions, especially the head. Your dog does remain conscious during the seizure. Your veterinarian will have to diagnose muscle contraction disease and provide specialized medications for the disorder.


If your dog has suffered from abuse or they are naturally shy, you may notice them jerk their head away when you reach for their head. This is a behavioral problem and it will not require medication. You may be able to work with a canine behaviorist to alleviate your dog’s fear. 


A simple toothache can cause your dog to jerk their head. Just like in humans, a toothache in a dog is painful and will cause them to act strangely. In some cases, medications may help with the toothache. Otherwise the affected tooth will need to be extracted. 

Vision Problems

Dogs that are experiencing vision problems may exhibit signs of jerking their head. Some dogs may only see shadows or blurred images causing them to startle or react when the shadows or blurred images move. 

Neck Problems

Stiff muscles in the neck can cause your dog to jerk his head in involuntary movements. Some neck problems are neurological. Your veterinarian will be able to diagnose the problem with your dog’s neck and begin treatments.

What to do if your Dog is Jerking His Head

It is always best to have your veterinarian check your dog out when you notice they are jerking their head. When you take your dog in for your veterinarian appointment be sure to bring with you any notes that you took regarding what occurs before and after the head jerking and any changes to the environment or diet.

After a full physical examination along with a complete blood count, biochemistry panel, urinalysis,and fecal exam, the veterinarian will evaluate the results of the diagnostic testing to determine the cause. Once a diagnosis has been made, your veterinarian will discuss with you the treatment options available. 

Dogs that are diagnosed with neurological disorders are usually able to be treated with medications to minimize the effects of the disorder. Be sure to follow your veterinarian’s instructions carefully to ensure that your dog is receiving the appropriate treatment.

Toothaches, depending on the severity of the tooth problem, will be treated with pain management medications, antibiotics and possible tooth extraction. 

Some dogs diagnosed with vision problems will not recover their vision, but you can create an environment where they feel safe and adjust your handling techniques so they are able to acknowledge your presence before you reach for them.

Prevention of Jerking His Head

It can be difficult to prevent neurological problems in your dog, especially if they are inherited. Neurological problems from a trauma or illness can also be hard to prevent. Have your dog’s eyes checked by a canine ophthalmologist every few years to ensure that there are no significant changes to their vision. Also, clean your dog’s teeth regularly. If your dog is not cooperative, you will need to have your veterinarian clean your dog’s teeth at least once a year although twice a year is better for your dog. 

Fear can be prevented by providing a positive atmosphere and being a confident leader for your dog. A canine behaviorist can work with you and your dog to overcome any fear from past experiences that may be causing your dog to be head shy and jerking their head away from your hand.

Cost of Jerking His Head

Depending on what is causing your dog to jerk his head and your demographic, the costs will vary. Treatment for a dog suffering from a neurological disorder can range in cost from $500 to $6500. Cavities and tooth extractions can cost between $500 and $2000. Vision problems can be diagnosed and treated from $250 to $2500.

Has Symptoms

Falling Over
focal seizures
decreased general proprioception

I have a 14 year old beagle mix who is still spry and full of energy like he is a pup. He recently started jerking his head/upper body in an up and down motion. At first it was a rare and slight occurrence but has now become more consistent and severe. It is happening multiple times a week, at least. His general proprioception in his hind legs is slow. Last week and this week he had an episode of vomiting multiple times, becoming extremely off balance and having NO general proprioception in his hind legs at all. Then after a few minutes he is back to normal and running around again. He will also occasionally fall over for seemingly no reason at all. Just last night he was sitting on my lap, his whole body began vigorously shaking and then he fell over and off the couch without warning but stood up right after and was back to normal. The jerking of his head can be interrupted. He has been examined by 2 veterinarians and a video and explanation of his symptoms have been consulted with 5+ veterinarians. I am also a veterinary technician and have consulted with a few other technicians that I have gotten to know over the years. No one seems to have any idea what is causing these strange symptoms. Some say tremors, some say focal seizures, overall everyone is just guessing at this point. His GGT, Bilirubin and Albumin were elevated on his full blood work that was completed last week. 3 view chest and abdominal radiographs were also completed and were normal. Any ideas would be helpful :)

Head jerking up and to the right

I have a ten year old long coated chihuahua she is being treated for leptoschlerosis. She has been on the medication Orbax for 6 weeks and is improving. She has had the disease for several months. She started jerking her head up and to the right for about 2 months. It has gotten more often and more repetitions. She is laying on her stomach when it happens and she is awake. It doesn't seem to bother her. My Vet hasn't seen her do this so she doesn't know what is wrong. She doesn't act like she has had a seizure. Can you tell me what you think is wrong. Thanks, Sandie

There are various possible causes for head jerking which may be related to the Leptospirosis, spinal issues, neurological issues among other causes; if the episodes are becoming more frequent, try to keep a record of when they occur and look for patterns. Your Veterinarian should also examine Zoey again to see if any new symptoms have presented since the last visit. Regards Dr Callum Turner DVM

Thank you. My Vet didn't think Leptospirosis would cause head jerking. I think that is the problem and hope it will stop when she no longer has the disease.

Head Jerking
Our dog will start with putting his head down on his paws and then his head will start to jerk. His behavior changes and he becomes needy and sometimes withdrawn. We have had our vet check him out and nothing was found wrong.
