Neurological signs are frightening because very different conditions can look alike. A dog who suddenly cannot balance may have an inner-ear disorder, a spinal injury, a seizure-related problem or a condition affecting the brain. Even low blood sugar or toxin exposure can mimic neurological disease.
Where the problem starts matters
The nervous system includes the brain, spinal cord and peripheral nerves. Disease in one area can cause different patterns of weakness, movement or awareness. A veterinarian evaluates posture, coordination, reflexes and the animal’s mental status to help locate the problem.
Examples of possible causes
Seizure disorders, inflammation, infection, degenerative conditions, disc disease, trauma, tumors, vestibular disease and certain metabolic or toxic problems can all affect movement or behavior. Age, breed, the pace of symptoms and exposure history help determine which conditions are more likely, but they cannot confirm one from a blog.
How diagnosis is approached
A neurological exam may be followed by blood and urine tests, imaging or referral for MRI and advanced assessment. An apparently “idiopathic” seizure diagnosis may require excluding other causes. Medication is then chosen for the condition, not simply because a dog shakes or tilts its head.
When to go immediately
New paralysis, inability to stand, loss of consciousness, prolonged seizures or repeated seizures is an emergency. Keep movement gentle in a dog who may have a spinal injury. Learn more in our guide to warning signs and treatment pathways.
