What is Catatonia?

The unresponsiveness seen in a catatonic state is not just your dog feeling down, but is a symptom of a more serious condition. Physical problems that can cause such a state, such as seizures and strokes, are usually preceded or followed by certain behaviors. Behavioral problems, such as fears and phobias, can also result in catatonia, which is usually triggered by a thing, event, or situation. Being aware of your dog’s behavioral changes, however subtle they may seem, can help to find the underlying cause to the disconnected state your dog is in.

Catatonia is a state of stupor or unresponsiveness seen sometimes in dogs, and can be due to various causes. If you have witnessed your dog remaining immobile, unaware or uncaring of the things and people around him and disconnected from his environment, he may be experiencing a catatonic state and should be examined by a veterinarian.

Symptoms of Catatonia in Dogs

Signs that your dog is experiencing catatonia can include:

  • Immobilization
  • Rigidity
  • Disconnection from environment
  • Decreased or no response to external stimuli
  • Staring into space or at an object for long periods of time

  • Remains still when touched
  • Automatic obedience
  • Lethargic
  • Unobservant
  • Refrains from barking, growling or making noise
  • Reduced interest in food
  • Decreased interest in exercise or play

Catatonia can be the result of a number of causes. Being aware of the symptoms of these causes can help you give your veterinarian the tools to properly diagnose your dog. Signs that may indicate a specific cause can include:

  • Altered behavior
  • Restlessness
  • Nervousness
  • Whining
  • Shaking
  • Salivating
  • Loss of consciousness
  • Spastic muscle activity
  • Snapping at invisible objects
  • Uncontrolled urination or defecation
  • Confusion
  • Disorientation
  • Pacing
  • Vision impairment or temporary blindness
  • Head tilt
  • Abnormal eye movements
  • Difficulties walking
  • Loss of balance and coordination
  • Circling
  • Loss of owner recognition
  • Collapse 
  • Escape behavior
  • Manic episodes
  • Withdrawal from fearful situations
  • Sudden anxiety
  • Pale gums
  • Vomiting

Causes of Catatonia in Dogs

Some of the possible reasons that a catatonic state may occur in your dog include:

Epilepsy and Seizures

Seizures are temporary and involuntary convulsions that involve uncontrolled muscle activity. When these episodes are repeated, it is referred to as epilepsy. Seizures can be caused by an inherited disorder, brain tumors or other trauma, liver or kidney disease, or through toxic poisoning. Often, seizures occur during changes in brain activity, such as during times of excitement or falling asleep. Before the seizure, there is often altered behavior, such as whining or shaking. Seizures generally last from five seconds to five minutes, at which time your dog may lose consciousness and experience a spastic full body muscle contraction. Afterwards, your dog may appear catatonic, disoriented, and confused.  


A stroke occurs when the brain’s blood supply has been disrupted or stopped, depriving the brain of oxygen and other critical nutrients. Most strokes are caused by a blood clot or as the result of disease or trauma. A stroke can result in symptoms of behavioral changes that include stupor, vision impairments, seizures, and difficulties walking. 


Anemia occurs when there is not enough red blood cells or hemoglobin circulating in the blood which results in a lack of oxygen available to the cells in the body. Characteristic pale gums often are a sign that this is occurring in your dog. 

Fears and Phobias

Fears can occur in any dog, and can become debilitating conditions. There are common fears, such as of new animals or situations, or fears that have evolved from trauma, such as from situations of abuse, neglect, malnourishment, or time in a shelter. Phobias are extreme responses of fearful behavior, and have progressed into routine responses that are triggered by certain stimuli, such as thunderstorms. Many of the behaviors seen in these dogs include episodes of mania or catatonia, with a decreased response to stimuli. 

Post-Traumatic Stress Disorder (PTSD)

Dogs can be affected by a past traumatic situation that causes this panic disorder. Specific triggers that cause the dog to remember the traumatic event results in a specific behavioral pattern that is individually characteristic to the dog. Behaviors can include an intense need to escape, anxiety, mania, and a state of catatonic stupor.  


Various drugs and treatments can adversely affect some dogs, and can create a lethargic state, such as aspirin or the popular anti-parasitic Ivermectin. Often, you will see other symptoms, such as vomiting and gastrointestinal distress.

Diagnosis of Catatonia in Dogs

A state of unresponsiveness can be tricky to diagnose. Be sure to tell your veterinarian about the symptoms you have noticed, the history of the catatonia, and any recent injuries or toxic exposures. Your vet will thoroughly examine your dog and may perform a neurological test. 

Blood tests can reveal the presence of anemia, a clotting abnormality, or a toxic substance. Along with urine tests, they can also assess any metabolic abnormalities, or organ disorders. Imaging techniques, such as CT scans, MRIs, or X-rays, can reveal tumors, trauma, or bleeding in the brain, and can verify if a stroke has occurred. An electrocardiogram may also be performed to assess the heart rhythm. Further testing can include a heartworm test, spinal tap, retinal exams, and endocrine and thyroid hormone testing. 

Abnormal behavior accompanies many of the causes of a catatonic state, and your vet may ask you several questions about your dog’s normal and recent behavior to determine if the catatonia is related to fears or phobias. Your vet may screen your dog for noise reactivity. Videotaping any odd behavior to present to your vet can help in this type of diagnosis. Once the cause of the catatonia is discovered, then an appropriate treatment plan can begin.

Treatment of Catatonia in Dogs

Treatment is aimed at treating the cause of the catatonia and can vary considerably. 

Seizures are commonly treated with anticonvulsant medication which is usually given for the duration of your dog’s life. Tumors may sometimes be removed, and any organ dysfunction will be treated. Stroke treatment involves hospitalization to administer oxygen therapy and intravenous therapy in an attempt to reduce any swelling in the brain and re-establish normal blood flow. Once stabilized, physical therapy may be recommended to increase mobility. Fluid therapy, corticosteroids, antioxidants, and other therapies can also be used. Severe anemia can be treated with blood transfusions, and the underlying cause of the anemia is treated appropriately. 

Behavioral issues that are at the root of the catatonia, such as phobias or PTSD, are treated by altering your dog’s response to the trigger stimuli. This includes techniques for relaxation, behavior modification, counter conditioning, desensitization, and quiet association. You should be able to recognize your dog’s triggers and have these techniques ready to use in those situations. For PTSD, it is important to keep your dog safe during times of panic. Medications can aid in relaxing your dog.

Recovery of Catatonia in Dogs

Recovery is variable and will depend on the underlying cause of the catatonia, how early treatment begins, and the state of your dog’s health. For acute situations, such as anemia caused by an infectious agent, treatment can eliminate the infection and return your dog to health. For a case of epilepsy, a lifetime of medication may be needed to keep symptoms from recurring. Stroke patients can have a full recovery if early diagnosis and treatment is available. Your veterinarian will discuss your dog’s chances of recovery based on his particular condition. 

At home, you may need to administer medications, or change your dog’s diet. Monitoring your dog for symptoms may be a lifelong necessity. Victims of a stroke may have a loss of function and can need consistent care.

Has Symptoms

shivers, stands still, salivates

I went to various vets but no solution. My dog is a mutt and was adopted by us at 4 months old. He is a wonderful happy dog and is now 11 and overall incredibly healthy and super fit for his age according to vets. However when he is not busy on a walk or socializing with humans or sleeping he has bouts of weird behaviour that has been happening over the last 4-5 year that I'm about to describe that can be "catatonic."

Note that he also has huge fears that make him shiver and press against my leg. These include rain sound (even slight,) loud wind noises, fireworks and shots (hunting activities) as well as certain alert sounds from mobile phones.

In his "catatonic" states he stands staring into space for 5 or more minutes (inside the house, or outside starting at the house and wont go in.) He also often licks and salivates a lot during the night and whimpers and paces. When this happens I check to see if he needs to go out and sometimes he wants to but afterwards it starts over again.

He is anxious and can't stay laying down for too long during day time.

At times he shakes his ears but they were checked by vet and get cleaned by me. He does have a history of ear infections. He is on anti-tick treatment/s most of the year.

Additionally there was an incident when he was about a year old that was horrible; he was accidentally choked by a leash that got stuck in car's wheel; he was drained of all energy but recovered after couple days of bed rest.

Has Symptoms

Trouble Walking
Uncontrolled urination
Staring into space

My dog got out of the gate as he does every so often and he came back to us fine after running away. My mom fed him and shortly after he ate, he started showing signs of stroke such as no control of his legs (not standing up properly), he was peeing himself, wasn’t responding to his name, not really walking anywhere, muscle spasms. My mom took him to the vet and they did a bunch of tests, unfortunately we don’t have enough money to keep him there overnight so they brought him back home to be brought back to the vet tomorrow. What can be done to fix this if anything? I read all of the symptoms for Catatonia and it seems like a match to what we’re seeing here with my dog.

The problem here isn’t the specific diagnosis, but what the underlying cause for the symptoms are which may include head trauma or poisoning; without examining Baxter I cannot start to think of a specific cause. You should keep Baxter calm for the time being and return to your Veterinarian in the morning. Regards Dr Callum Turner DVM
