WHAT BRAIN TUMORS IS — AND WHAT IT MEANS FOR YOUR DOG
A brain tumor is an abnormal mass of cells inside or surrounding the brain.
They can be:
Primary tumors
Originate in the brain:
• Meningioma (arising from meninges; most common)
• Glioma (astrocytoma, oligodendroglioma; highly aggressive)
• Choroid plexus tumors
• Pituitary tumors
• Ependymoma
Secondary tumors
Spread from elsewhere:
• Lymphoma
• Hemangiosarcoma
• Metastasis from other organs
Primary tumors are more common, particularly in older dogs
MOST COMMON TYPES OF BRAIN TUMORS IN DOGS
1. Meningioma
• Most common brain tumor in dogs
• Arises from meninges (outer brain covering)
• Often slow-growing
• Frequently well-defined
• Most surgically resectable
• Best prognosis
MEDICINAL MUSHROOMS
• More common in brachycephalic breeds
• Boxers
• Boston Terriers
• Bulldogs
• French Bulldogs
• Invasive
• Difficult to remove surgically
• Responds well to radiation
3. Pituitary Tumors
• Cause neurological signs + endocrine disorders
• Treatable with radiation
4. Choroid Plexus Tumors
• Cause hydrocephalus (fluid buildup)
• Surgical removal sometimes possible
5. Metastatic Brain Tumors
• Spread from systemic cancers
• Treatment depends on primary cancer
BREEDS AT HIGHER RISK
Gliomas (brachycephalics)
• Boxers
• Boston Terriers
• French Bulldogs
• English Bulldogs
• Pugs
Meningiomas (dolichocephalics)
• Golden Retrievers
• German Shepherds
• Collies
• Labs
Any dog can develop a brain tumor, but age is the strongest risk factor.
SYMPTOMS OF BRAIN TUMORS IN DOGS
Symptoms depend on location, growth rate, and tumor type.
Most common signs
• Seizures (especially first-time seizures in older dogs)
• Circling
• Head pressing
• Behavior or personality changes
• Disorientation
• Vision loss
• Walking in circles
• Head tilt
• Stumbling / ataxia
• Facial asymmetry
• Sudden aggression
• Vocalization
• Tremors
Emergency signs
• Continuous seizures (status epilepticus)
• Cluster seizures
• Collapse
• Coma
These require immediate ER care.
HOW URGENT IS A BRAIN TUMOR?
If seizures are present:
This is an urgent condition. Treatment should begin immediately.
If neurologic signs are progressive:
Evaluation within 1–7 days is recommended.
If your dog is stable but symptomatic:
MRI should be scheduled within 1–2 weeks to confirm diagnosis and begin treatment.
DIAGNOSING BRAIN TUMORS
1. MRI (Magnetic Resonance Imaging) — Gold Standard
Shows:
• Tumor size
• Location
• Tissue invasion
• Mass effect (swelling)
• Hydrocephalus
• Surgical candidacy
MRI is essential for definitive diagnosis.
2. CT Scan
Less detailed than MRI but sometimes used in emergencies.
3. CSF Tap (Cerebrospinal fluid analysis)
Used to rule out:
• Meningitis
• Infectious disease
(Not always recommended if pressure is very high — risk of herniation.)
4. Bloodwork
Checks:
• Organ function
• Endocrine abnormalities
• Infection
• Inflammatory markers
5. Hormone testing
Useful for pituitary tumors
TREATMENT OPTIONS FOR BRAIN TUMORS IN DOGS
PROGNOSIS FOR BRAIN TUMORS
Survival depends heavily on tumor type and treatment.
MENINGIOMA
• Surgery alone: 6–12 months
• Surgery + radiation: 18–36+ months
• Radiation alone: 12–24 months
• Palliative care only: 2–4 months
GLIOMA
• Radiation: 9–18 months
• Radiation + chemo: 10–20 months
• Palliative care only: 2–4 months
PITUITARY TUMORS
• Radiation: 12–36 months
CHOROID PLEXUS TUMORS
• Highly variable
• If causing hydrocephalus → guarded prognosis
QUALITY OF LIFE AND WHAT TO EXPECT
Most dogs enjoy good quality of life for months to years with combination therapy.
After surgery
• Rapid improvement
• Dogs adapt extremely well
• Temporary disorientation is common
During radiation
• Mild fatigue
• Temporary inflammation
• Long-term benefit significant
During palliative care
• Good appetite
• Reduced seizures
• Increased engagement
• Comfort focused
WHAT NOT TO DO
• Do NOT delay MRI after first adult-onset seizure
• Do NOT stop seizure meds abruptly
• Do NOT avoid steroids when recommended
• Do NOT compare your dog’s prognosis to human brain cancer
• Do NOT push aggressive treatment if your dog’s comfort is declining
• Do NOT give supplements without veterinary guidance
WHEN TO SEEK EMERGENCY CARE
Go to ER immediately if:
• Cluster seizures
• Seizure lasting >3 minutes
• Collapse or coma
• Sudden blindness
• Inability to walk
• Crying in pain
• Projectile vomiting
• Severe disorientation
QUESTIONS TO ASK YOUR VETERINARIAN OR ONCOLOGIST
diagnosis
• Does my dog need an MRI urgently?
• Could this be something other than cancer?
treatment
• Is surgery recommended?
• Should we combine surgery with radiation?
• Should we start steroids immediately?
• Is Keppra the right seizure medication?
Prognosis
• What is my dog’s expected timeframe?
• What symptoms indicate decline?
Integrative care
• What supplements support brain health?
• What diet will help with inflammation?
FREQUENTLY ASKED QUESTIONS (SEO BLOCK)
Is my dog in pain?
Not always. Brain tumors cause neurological dysfunction more often than pain.
Can a dog survive a brain tumor?
Yes — many dogs live 6–24 months or longer with surgery or radiation.
Do brain tumors cause seizures?
Yes — seizures are one of the most common signs.
Is MRI necessary?
Yes — it is essential for diagnosis and staging.
Can brain tumors be cured?
Some meningiomas can be surgically cured.
