Brain disease in dogs shows up as seizures, balance/coordination issues (circling, stumbling, head tilt), sudden behavioral changes (aggression, confusion, clinginess), vision/hearing loss, and cognitive decline (house-soiling, disorientation in familiar places, sleep pattern changes). These symptoms vary by the affected brain area but often include neurological signs like tremors, weakness, and abnormal eye movements (nystagmus).
Physical Signs of Neurological Challenges in Dogs
They could start to tilt their head to one side. An inability to walk straight forward because of poor coordination. Discomfort or pain while handling or being touched. Uncontrollably twitching or trembling muscles.
There can be a variety of neurological symptoms from brain trauma that your pet may experience. Motor control issues such as circling in one direction, head tilting or displaying rapid or abnormal eye movement, or a difference in the size of the pupils may be present. Your pet may experience seizures.
Changes in Behavior
One of the first signs of a brain tumor in dogs is a noticeable shift in behavior. Dogs may display aggression, confusion, or anxiety that was not present before. These behavioral changes occur because the tumor affects brain function, altering how your dog processes information and emotions.
As a pet owner you must be aware that certain medications of this type are given for the duration of the pet's life. Reality must be faced when a pet is given the diagnosis of brain tissue inflammation. Dogs with this condition usually survive on average six months after symptoms become apparent.
Steroids for Reducing Inflammation and Swelling:
Veterinarians usually prescribe steroids like Prednisone to reduce inflammation and swelling in the brain or spinal cord. These medications effectively manage conditions like encephalitis or meningitis, relieving our dogs.
Pituitary gland adenoma
This tumor causes excessive production of cortisol from the adrenal cortex which leads to the classic signs of alopecia (hair loss), polyuria (excessive urination), polydipsia (excessive water drinking), and a pot-bellied appearance of the abdomen due to muscle break down. See picture here.
Some of the first signs of a brain tumor may include:
Sometimes affected animals behave as if they are in pain. Seizures are a classic sign of forebrain disease and in fact, new onset of seizures is the most common presenting sign of animals with tumors of the forebrain.
Brain tumors occur in any age, breed and sex, but most commonly middle aged and older dogs (>5 years) are affected. Some breeds that appear to be over-represented include the golden retriever, boxer, Doberman Pinscher, Scottish terrier, and the Old English Sheepdog.
Clinical signs of encephalitis
Seizures, blindness, behavior changes, mental depression and circling are seen with forebrain (cerebral) disease. Imbalance or incoordination, head tilt, tremors or facial paralysis are associated with brainstem disease.
Headache, dizziness, confusion, and fatigue tend to start immediately after an injury but resolve over time. Emotional symptoms such as frustration and irritability tend to develop during recovery.

Common symptoms of neurological disorders include:
A spinal fluid analysis can show if there is any inflammation or infection in the brain that may be causing episodes. Despite a spinal tap being important for a diagnosis, an MRI is performed first in most cases because it can help determine if a spinal tap is safe to perform.
Small brachycephalic dog breeds, such as the pug and French bulldog, are prone to develop specific neurological conditions and spinal disorders in particular. One group of conditions heavily associated with the body conformation of these dogs are vertebral and spinal malformations.
Brain Tumor Symptoms in Dogs
General signs and symptoms caused by brain tumors may include: Headache or pressure in the head that is worse in the morning. Headaches that happen more often and seem more severe.
Often, dogs are humanely euthanized within six to twelve months after the onset of clinical signs, due to the debilitating loss of mobility caused by this disease. Without euthanasia, DM can progress for more than three years and lead to an inability to walk or even breathe normally.
Brain tumor red flags include persistent, worsening headaches (especially in the morning/night), new-onset seizures, unexplained nausea/vomiting, vision changes (blurred, double), balance/coordination issues (clumsiness, trouble walking), significant personality or behavioral shifts, weakness/numbness on one side, and speech difficulties (slurring, trouble finding words). These symptoms often stem from increased pressure or direct interference with brain functions, and their gradual or sudden appearance warrants medical attention.
Brain tumor misdiagnosis can commonly be diagnosed as these diseases:
Experiencing non-existent foul smells and odours could be sign of cancer growing in the olfactory cortex or invading it from neighbouring tissues.
The most common sign is epileptic seizures, particularly when seizures occur in a dog over seven years of age. Other signs include behavioural changes such as vacancy, frequent disorientation and loss of normal training; wobbliness, weakness and blindness.
Warning signs a dog is dying include significant lethargy, loss of appetite/thirst, difficulty breathing (labored, panting at rest), incontinence (bladder/bowel), confusion, restlessness or withdrawal, decreased mobility (weakness, stumbling), and increased signs of pain (whining, aggression) as their body systems begin to shut down. These physical and behavioral changes signal a decline, and consulting your vet is crucial for guidance on comfort and quality of life.
Brain tumors are encountered more often in middle-aged to older dogs and cats, most being over 9 years old at the time of diagnosis. Meningioma is the most common primary brain tumor found in both dogs and cats; it arises from the tissue lining the brain.
