TLDR
Neurology in veterinary medicine focuses on diagnosing and treating disorders of the brain, spinal cord, nerves, and muscles in dogs, cats, and other pets. Common neurological issues include seizures, intervertebral disc disease (IVDD), vestibular disease, meningitis, neuropathies, and mobility disorders. Southern Ocean Animal Hospital uses advanced diagnostic tools—including neurological exams, laboratory tests, digital radiography, ultrasound, in-house blood analyzers, and referral-access MRI/CT—to identify conditions early and create effective treatment plans. Daniel N. Pascetta, DVM, evaluates each patient with a thorough, systematic neurological approach to ensure accuracy, safety, and compassionate care.
ELI5 (Explain Like I’m Five)
A pet’s nervous system is like a big communication network. The brain sends messages through nerves to help a pet walk, blink, eat, see, feel, and stay balanced.
When something goes wrong in that network—like a bad wire (nerve), a swollen switch (spinal cord), or a glitch in the computer (brain)—a pet might stumble, have a seizure, tilt their head, or act confused.
Neurology helps veterinarians figure out where the problem is and how to fix it.

Understanding Veterinary Neurology
Veterinary neurology is the branch of internal medicine focused on diseases affecting the nervous system of dogs, cats, and other pets. The nervous system is divided into two major parts:
- Central nervous system (CNS):
Brain and spinal cord - Peripheral nervous system (PNS):
Nerves outside the brain and spinal cord, neuromuscular junctions, and muscles
These structures work together to control:
- Balance
- Coordination
- Vision and hearing
- Limb movement
- Reflexes
- Consciousness
- Behavior
- Pain response
When one part malfunctions, the entire system can be affected. A pet may show subtle or dramatic symptoms, and determining exactly where the problem originates is the foundation of neurological diagnosis.
Southern Ocean Animal Hospital uses a structured, step-by-step neurological evaluation guided by Daniel N. Pascetta, DVM, whose medical training at one of the nation’s top veterinary schools provides a highly advanced approach to neurological problem-solving.
Why Neurological Evaluations Are Important
Neurological disorders are often complex. Two pets with similar symptoms may have entirely different causes. For example:
- A dog that cannot walk could have IVDD, spinal trauma, a brain tumor, or metabolic disease.
- A cat with head tilt could have ear disease, vestibular syndrome, or a toxin exposure.
- A pet with seizures might have epilepsy, infection, brain tumor, or liver disease.
A neurological exam allows Dr. Dan to:
- Localize the lesion (brain, spinal cord, peripheral nerves).
- Identify severity.
- Prioritize urgent findings.
- Select appropriate diagnostics.
- Initiate treatment quickly when needed.
Common Neurological Conditions in Dogs, Cats, and Other Pets
Seizures (Epilepsy and Non-Epileptic Causes)
Seizures are one of the most common neurological emergencies. Causes include:
- Idiopathic epilepsy (often hereditary)
- Brain tumors
- Toxins
- Metabolic disorders (liver disease, kidney disease)
- Trauma
- Infections such as meningitis or encephalitis
- Immune-mediated disease
Intervertebral Disc Disease (IVDD)
More common in dogs—particularly Dachshunds, Beagles, Chihuahuas, Corgis, Shih Tzus.
Symptoms include:
- Back pain
- Hind-limb weakness
- Trouble standing
- Dragging limbs
- Loss of bladder/bowel control
Immediate evaluation is crucial.
Vestibular Disease
Often described as “old dog vestibular disease,” but can occur at any age.
Signs:
- Head tilt
- Rapid eye movements (nystagmus)
- Falling to one side
- Inability to walk normally
Causes include inner ear infections, idiopathic vestibular disease, toxins, inflammation, or tumors.
Meningitis and Encephalitis
Inflammation of the brain or spinal cord membranes. Causes include:
- Immune-mediated disease
- Viral infection
- Bacterial infection
- Fungal infection
- Tick-borne disease
Symptoms may include fever, pain, neck stiffness, or behavioral changes.
Neuropathies
These affect the peripheral nerves.
Examples:
- Facial nerve paralysis
- Laryngeal paralysis
- Diabetic neuropathy
- Tick paralysis
- Trauma-related nerve injury
Brain Tumors
More common in older pets. Symptoms vary depending on tumor location.
Congenital Neurological Disorders
Examples:
- Hydrocephalus
- Cerebellar hypoplasia
- Spinal malformations
How Daniel N. Pascetta, DVM, Performs a Comprehensive Neurological Exam
A structured neurological exam forms the foundation for all advanced diagnostics.
Step 1: Mental Status & Behavior
Checks alertness, response to voice, response to touch, and environmental awareness.
Step 2: Gait & Movement
Pets are observed walking to assess:
- Coordination
- Weakness
- Stumbling
- Ataxia
- Head bobbing
Step 3: Postural Reactions
Tests ability to reposition paws and maintain balance.
Step 4: Cranial Nerve Assessment
This includes:
- Vision tests
- Pupil light reflex
- Facial movement
- Palpebral reflex
- Gag reflex
Step 5: Spinal Reflexes
Reflex testing helps identify spinal cord lesions.
Step 6: Pain Perception and Spinal Palpation
Checks for spinal pain, muscle tension, and nerve sensitivity.
Dr. Dan’s methodical training ensures neurological localization is precise before ordering tests.

Lifestyle and Environmental Adjustments
- Flooring changes
- Ramps
- Harnesses
- Controlled activity plans
Example Scenario (Realistic, Pet Owner–Friendly)
A middle-aged Beagle arrives unable to walk on his hind legs. Dr. Dan performs:
- Neurological exam: Suggests thoracolumbar spinal cord lesion.
- X-rays: Rule out fractures.
- Pain response testing: Indicates severe nerve compression.
- Referral MRI: Confirms IVDD.
- Treatment plan: Emergency pain control, neurologist referral for surgery.
The owner receives clear explanations and a step-by-step plan. The dog walks again after recovery.

What-If Situations Pet Owners Commonly Worry About
“What if my pet suddenly collapses?”
Immediate evaluation is essential. Many causes are treatable if addressed early.
“What if my dog has a seizure but then seems normal?”
Still requires a neurological workup; many underlying conditions repeat or worsen.
