Why does my dog's head nod when lying down, like a heartbeat?

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

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

It almost sounds like you are describing narcolepsy/cataplexy. This is a disease that is usually inherited so it would be strange for you to seen signs now, although it can be associated with some other diseases. Other possibilities would be a heart condition, hypoglycemia related to pancreatic disease, or neurologic diseases like myasthenia gravis. I would recommend having her examined by your veterinarian. It could be helpful for you to video an episode before your appointment if possible.

Bonnie's abnormalities walking and head bobbing this morning sound as though they may have occurred due to a seizure. I'm glad that it only lasted 1-2 minutes, but seizures can have a "post-ictal" period afterwards where the animal can be a bit stressed for another few minutes to hours. Seizures can occur due to a number of reasons, including epilepsy for unknown reasons, toxin exposure, liver shunts (abnormal blood flow and toxin filtration) and brain tumors. For a first time possible seizure, there are generally no necessary treatments or diagnostics. However, closely monitor Bonnie for a recurrent episode. If one occurs, try to video record her actions so that her vet will be able to watch it. Also keep a log of any future episodes with the date, time, duration of possible seizure and any changes in behavior or lifestyle beforehand. If Bonnie ever has 2 or more seizures in a 24 hour period, or has a seizure that lasts for much longer than 5 minutes, she should go to an ER immediately, as this would indicate a "cluster" of seizures and require immediate medication.

If you can call Piper's name and she stops, and if she seems to be her normal self otherwise it's possible that she is having an idiopathic head tremor. The cause of the tremors is unknown but they occur in many breeds and usually are not harmful. If she has had any seizures, if she seems disoriented, or if she seems painful I'd recommend seeing your veterinarian.

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.
