About the Cavalier King Charles Spaniel

The Cavalier King Charles Spaniel (CKCS) is one of the most beloved companion breeds worldwide, renowned for their gentle, affectionate temperament and expressive, soulful eyes. Named after King Charles II of England who was famously devoted to his spaniels, the breed was refined in the 20th century to recreate the flat-skulled toy spaniels depicted in Old Master paintings. Their sweet nature and moderate size (5.9–8.2 kg / 13–18 lbs) make them exceptional therapy dogs and family companions. However, their limited gene pool and selective breeding have created significant health vulnerabilities — most notably mitral valve disease and syringomyelia — that require informed, proactive management throughout their senior years.

When Does a Cavalier Become a Senior?

Cavalier King Charles Spaniels are generally considered senior at age 7–8 years, though cardiac screening should begin much earlier due to the breed's extreme predisposition to mitral valve disease. As a small-to-medium breed, their average lifespan is approximately 9–12 years (VetCompass median: 10.7 years), somewhat shorter than other breeds of similar size due to the high prevalence of cardiac disease.

Key Statistics & Research Data

Mitral Valve Disease (MVD): Lifetime prevalence approaches 100% — 20x more prevalent than in other breeds (Hezzell, 2025; NCSU)
50% of Cavaliers develop MVD murmurs by age 5, nearly all by age 10
Syringomyelia (SM): 41% incidence in screened populations; >90% have Chiari-like malformation (CM)
PSOM (Primary Secretory Otitis Media): Up to 50% of Cavaliers affected — virtually unique to the breed
Cardiac disorders: 31.7% — most common disorder category (Summers et al., 2015, PMC4579365)
Dermatological disorders: 22.2% — second most common category
Ocular disorders: 20.6% — including dry eye/curly coat syndrome
Episodic Falling Syndrome: Breed-specific paroxysmal exercise-induced dystonia
Macrothrombocytopenia: Common asymptomatic platelet abnormality in the breed
MVD is the leading cause of death in Cavalier King Charles Spaniels

Key Health Concerns for Senior Cavaliers

Mitral Valve Disease (MVD)

The defining health challenge for Cavalier King Charles Spaniels. MVD causes progressive degeneration of the heart's mitral valve, leading to regurgitation and eventually congestive heart failure. The disease is 20 times more prevalent in Cavaliers than other breeds, with lifetime prevalence approaching 100%. The EPIC trial (2016) demonstrated that [pimobendan](https://seniorpet.org/knowledge/pimobendan-vetmedin-heart-failure-guide "Pimobendan Heart Failure Guide") started at Stage B2 delays onset of heart failure by approximately 15 months.

| Stage | Description | Management | |-------|-------------|------------| | A | At risk (all Cavaliers) | Annual cardiac auscultation from age 1 | | B1 | Murmur present, no enlargement | Echocardiogram every 6–12 months | | B2 | Heart enlargement confirmed | Start pimobendan (EPIC protocol) | | C | Congestive heart failure | Multi-drug therapy (pimobendan + furosemide + ACE inhibitor) | | D | Refractory heart failure | Intensive care, palliative options |

Syringomyelia & Chiari-like Malformation (SM/CM)

Over 90% of Cavaliers have Chiari-like malformation — a condition where the skull is too small for the brain, causing the cerebellum to herniate through the foramen magnum. This obstructs cerebrospinal fluid flow and causes syringomyelia (fluid-filled cavities in the spinal cord) in approximately 41% of screened dogs. Symptoms include phantom scratching, neck pain, sensitivity to touch, and progressive neurological deficits.

PSOM (Primary Secretory Otitis Media)

A condition virtually unique to Cavaliers where a viscous mucus plug fills the middle ear cavity. Affects up to 50% of the breed. Often misdiagnosed as SM due to overlapping symptoms (head/neck pain, scratching at ears). Diagnosis requires myringotomy or CT/MRI imaging.

Episodic Falling Syndrome (EFS)

A breed-specific paroxysmal exercise-induced dystonia caused by a mutation in the BCAN gene. Affected dogs experience episodes of increased muscle tone and collapse during exercise or excitement. DNA testing is available.

Keratoconjunctivitis Sicca & Curly Coat Syndrome

Cavaliers are predisposed to dry eye (KCS), and a breed-specific variant called "curly coat/dry eye syndrome" (congenital keratoconjunctivitis sicca and ichthyosiform dermatosis) is caused by a FAM83H gene mutation. This severe condition presents at birth with rough, curly coat and absent tear production.

Preventive Care Schedule

| Age | Key Actions | |-----|-------------| | 1–5 years | Annual cardiac auscultation, baseline echocardiogram by age 3, MRI screening for CM/SM if breeding | | 5–7 years | Biannual cardiac exams, echocardiogram annually, neurological assessment, eye exam (Schirmer test) | | 7–9 years | Senior bloodwork, cardiac monitoring every 3–6 months, pain assessment for SM, dental cleaning | | 9–12 years | Quarterly cardiac checks, [quality of life](https://seniorpet.org/knowledge/[siamese](https://seniorpet.org/knowledge/breed/siamese "Senior Siamese Cat Health Guide")-cat-quality-of-life "Quality of Life Assessment") scoring, medication optimization, comfort-focused care | | 12+ years | Palliative care planning, frequent small meals, mobility support, pain management |

Daily Care

Cavalier King Charles Spaniel History: From Royal Courts to Modern Companion — The Cavalier King Charles Spaniel descends from small toy spaniels popular in Renaissance and 17th-century England, famously favored by King Charles II. Victorian breeding produced the shorter-faced King Charles Spaniel; early 20th-century enthusiasts revived the older, longer-muzzled type to create the modern Cavalier. Today Cavaliers are beloved affectionate companions with a gentle temperament and predispositions to heart and neurological conditions.
Cavalier King Charles Spaniel Physical Characteristics: Four Color Varieties & Breed Standard — Compact, graceful toy spaniels, Cavaliers stand about 12–13 inches (30–33 cm) at the withers and typically weigh 13–18 lb (6–8 kg). They have a flat skull, large dark round eyes, a moderate stop, tapered muzzle, long feathered ears and a silky, flat or slightly wavy coat with feathering on chest, legs and tail. Recognized colors: Blenheim, tricolor, ruby and black‑and‑tan.
Cavalier King Charles Spaniel Grooming & Coat Care: Maintaining the Silky Coat in Senior Years — Senior Cavaliers (commonly 7–8+ years) need gentle daily-to-every-other-day brushing to prevent mats, feather trims as needed, and baths only every 4–6 weeks with a mild shampoo. Clean ears and eyes regularly, inspect skin for lumps or irritation, and maintain balanced nutrition with omega‑3 fatty acids (vet‑approved). Sudden coat thinning, dullness, or excessive shedding warrants veterinary evaluation for conditions like hypothyroidism.
Dental Care for Senior Cavalier King Charles Spaniels: Prevention & Treatment of Periodontal Disease — Senior Cavalier King Charles Spaniels have elevated periodontal risk (breed survey 15.2%). Prevent with daily toothbrushing, dental diets/chews, tartar-control water additives, routine oral exams and professional cleanings under anesthesia. Treat established disease with scaling/root planing, extractions when necessary, systemic/topical antibiotics and pain control, plus regular rechecks and strict homecare coordinated with your veterinarian or dental specialist.
Ear Care for Cavalier King Charles Spaniels: Managing Long Ears, Otitis & PSOM Awareness — Cavalier King Charles Spaniels need weekly ear inspections and gentle cleaning with a veterinarian‑recommended solution to remove wax, dry the canal, and prevent otitis; avoid cotton swabs and over‑cleaning. Keep long pinnae and surrounding hair trimmed and ears dry after swimming. Recurrent infections, persistent discharge, head tilt or hearing loss may indicate PSOM—seek prompt veterinary ENT evaluation with otoscopy and imaging.
Creating a Comfortable Home for Your Senior Cavalier: Mobility Aids, Bedding & Environmental Modifications — Provide low, stable ramps and non-slip surfaces; use a supportive sling or mobility harness for rises. Offer orthopedic, low-entry beds with memory foam and extra padding; add heated pads if arthritis is present. Raise food/water bowls, add night lighting, secure stairs, and use baby gates to limit jumping. Schedule veterinary evaluation for cardiac or syringomyelia-related pain and consider physiotherapy or hydrotherapy.
Veterinary Visit Schedule for Senior Cavalier King Charles Spaniels: What to Expect & When — Senior CKCS (≈8+ years) should see a vet every 6 months for cardiac auscultation, weight/BCS, blood pressure and symptom checks. Annual full exams with CBC/chemistry, urinalysis, thyroid testing and dental assessment are recommended. Obtain a baseline echocardiogram if not done; repeat echo every 6–12 months if a murmur or MMVD is present. Ophthalmic and orthopedic checks yearly.

Behavior

Cavalier King Charles Spaniel Temperament & Behavior Changes in Senior Years — Cavalier seniors commonly show reduced activity, increased clinginess or irritability, sleep‑wake changes, disorientation and house‑soiling from canine cognitive dysfunction; concurrent myxomatous mitral valve disease (MMVD)—the breed’s leading cardiac condition and common cause of cardiac death—can cause exercise intolerance, coughing, restlessness or syncope, worsening behavior and quality of life; veterinary assessment is recommended. ([pubmed.ncbi.nlm.nih.gov](https://pubmed.ncbi.nlm.nih.gov/41442884/?utm_source=openai))
Separation Anxiety in Cavalier King Charles Spaniels: Prevention & Management for the Velcro Breed — Cavalier King Charles Spaniels are prone to separation anxiety due to strong human attachment. Prevent and manage it with early socialization, gradual desensitization to departures, consistent routines, daily exercise and mental enrichment (puzzle feeders, scent games), safe confinement/crate training, and brief absence practice. For moderate–severe cases combine behavior modification with veterinary guidance for medications (e.g., fluoxetine, trazodone) and a veterinary behaviorist.
Socialization & Multi-Pet Households: Senior Cavalier King Charles Spaniels Living with Other Animals — Senior Cavalier King Charles Spaniels usually remain sociable with other household animals but may show increased irritability or withdrawal from pain, sensory decline, or cognitive change. Use gradual, supervised introductions; maintain separate beds, food and litter areas; provide elevated ramps, non‑slip surfaces and quiet retreat spaces; monitor for resource guarding or mobility-related aggression; consult your veterinarian to rule out pain or medical causes before behavior modification.
Pain Recognition in Senior Cavalier King Charles Spaniels: Identifying Hidden Discomfort from SM, MVD & Arthritis — Senior Cavalier King Charles Spaniels often mask pain; watch for subtle signs of syringomyelia (neck/back sensitivity, phantom‑scratching, yelping, head/neck aversion), mitral valve disease (exercise intolerance, coughing, rapid breathing, weakness or fainting), and arthritis (stiffness after rest, difficulty rising, reduced jumping, altered gait). Changes in appetite, sleep, grooming, or increased clinginess also suggest hidden discomfort—seek veterinary assessment.

Prevention

Cavalier King Charles Spaniel Lifespan: Statistics, Factors & How to Maximize Longevity — The average Cavalier King Charles Spaniel lives about 10–12 years (range ~9–14). Major lifespan threats include myxomatous mitral valve disease (MMVD), syringomyelia, and cancer. Maximize longevity with annual cardiac screening (auscultation and echocardiography if murmurs), weight and dental care, balanced nutrition, parasite control, regular veterinary exams, prompt neurologic evaluation, and choosing dogs from health‑tested breeders.
Senior Cavalier King Charles Spaniel Health: Complete Screening & Prevention Guide — For senior Cavalier King Charles Spaniels (generally ≥8 years): annual wellness exam plus CBC, chemistry, T4, urinalysis and blood pressure; dental cleaning with oral radiographs; cardiac auscultation every visit and echocardiogram if a murmur or every 6–12 months with known MMVD; neurologic/orthopedic and ophthalmic exams; thoracic radiographs as indicated. Maintain weight, a balanced senior diet, dental care and parasite prevention.
Genetic Testing for Cavalier King Charles Spaniels: Available DNA Tests & What They Mean — Key DNA tests for Cavalier King Charles Spaniels include SOD1 testing for degenerative myelopathy, BCAN-based testing for Episodic Falling, and CC/DE (FAM83H) testing for Curly Coat/Dry Eye—available from major labs. ([vgl.vetmed.ucdavis.edu](https://vgl.vetmed.ucdavis.edu/test/degenerative-myelopathy?utm_source=openai)) Mitral valve disease (MMVD) is polygenic with no single predictive DNA test; cardiac screening (auscultation/echocardiography) is advised. ([pubmed.ncbi.nlm.nih.gov](https://pubmed.ncbi.nlm.nih.gov/30974015/?utm_source=openai)) Chiari‑like malformation/syringomyelia is diagnosed by MRI and screened under BVA/KC schemes. ([royalkennelclub.com](https://www.royalkennelclub.com/health-and-dog-care/health-dog-care/health/getting-started-with-health-testing-and-screening/cmsm-screening-scheme/?utm_source=openai))
Cardiac Screening Protocols for Cavalier King Charles Spaniels: When, How & Why Regular Heart Checks Save Lives — Cavalier King Charles Spaniels should have yearly cardiac auscultation beginning by 6 to 12 months and annually thereafter; dogs intended for breeding should have a cardiology exam and echocardiogram (commonly recommended by 2.5 years) and enter kennel‑club heart schemes. If a murmur or mitral regurgitation is found, repeat cardiology and echo every 6–12 months to monitor progression. ([pmc.ncbi.nlm.nih.gov](https://pmc.ncbi.nlm.nih.gov/articles/PMC6524084/?utm_source=openai))
Neurological Monitoring for Cavalier King Charles Spaniels: Tracking SM/CM Progression & When to Intervene — For Cavalier King Charles Spaniels (CKCS), monitor CM/SM with a baseline neurologic exam and MRI if signs or for breeding assessment. Recheck neurologic exams every 6–12 months (sooner if new/worse signs). Repeat MRI when clinical signs emerge or progress, or if prior imaging showed syrinx progression. Intervene medically or surgically when persistent neuropathic pain, progressive deficits, or MRI-confirmed progression matches clinical deterioration.
Quality of Life Assessment for Senior Cavalier King Charles Spaniels: The HHHHHMM Scale & Beyond — Use the HHHHHMM quality-of-life scale—Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, More good days than bad—to assess senior Cavalier King Charles Spaniels. Because CKCS commonly develop progressive myxomatous mitral valve disease, syringomyelia and dental/ocular issues, pair regular HHHHHMM scoring with cardiac monitoring, pain control, weight management, tailored exercise and timely palliative or euthanasia planning with your veterinarian.
Longevity Strategies for Cavalier King Charles Spaniels: Evidence-Based Approaches to Maximize Lifespan & Healthspan — Cavalier longevity centers on preventing and managing myxomatous mitral valve disease (MMVD). Annual cardiac screening (auscultation and echocardiography for high‑risk or breeding dogs), weight control, dental care, and regular exercise reduce risk. Early medical therapy—pimobendan for echocardiographic cardiomegaly (ACVIM stage B2)—delays heart failure. Responsible selective breeding based on heart screening lowers MMVD prevalence.

Chronic Disease

Mitral Valve Disease in Cavalier King Charles Spaniels: The Complete Guide to Diagnosis, Staging & Treatment — Mitral valve disease in Cavalier King Charles Spaniels is progressive myxomatous degeneration causing mitral regurgitation. Diagnosis uses auscultation, thoracic radiographs, echocardiography (to assess valve morphology, regurgitant volume and chamber size) and biomarkers (NT‑proBNP). Staging follows ACVIM (A–D). Management: asymptomatic monitoring; once heart failure develops, pimobendan, diuretics (furosemide), ACE inhibitors, sodium restriction and regular rechecks improve survival and quality of life.
Syringomyelia & Chiari-like Malformation in Cavaliers: Symptoms, Diagnosis & Management — Chiari‑like malformation (CM) in Cavalier King Charles Spaniels often leads to syringomyelia (SM), causing neck pain, phantom‑scratching at the neck/shoulders, head rubbing, sensitivity, scoliosis or weakness, and behavioral change. Diagnosis requires neurologic examination and MRI of the skull/cervical spine. Management includes pain control (gabapentin/pregabalin, judicious NSAIDs), physical therapy and weight control; severe cases may need surgical decompression or syrinx shunting. Affected dogs should not be bred.
PSOM (Glue Ear) in Cavalier King Charles Spaniels: The Hidden Cause of Pain & Scratching — Primary secretory otitis media (PSOM, “glue ear”) in Cavalier King Charles Spaniels is accumulation of thick mucous in the middle ear causing head rubbing, ear scratching, pain, hearing loss, head tilt and vestibular signs. Diagnosis uses otoscopy and middle‑ear imaging (CT/MRI) or myringotomy. Definitive treatment is myringotomy with flushing ± steroid/antibiotic therapy; recurrence may require repeat procedures or tympanostomy tube placement.
Episodic Falling Syndrome in Cavalier King Charles Spaniels: Genetic Testing & Management — Episodic Falling Syndrome in Cavalier King Charles Spaniels is caused by a recessive mutation in the brevican (BCAN) gene; affected dogs are homozygous while carriers are asymptomatic. A validated DNA test identifies affected and carrier dogs for informed breeding. Management is supportive: avoid exercise/excitement triggers, optimize weight and environment, and use veterinary-directed symptomatic therapy tailored to each dog.
Eye Conditions in Senior Cavalier King Charles Spaniels: Dry Eye, Cataracts & Retinal Disease — Senior Cavalier King Charles Spaniels commonly develop keratoconjunctivitis sicca (dry eye), age-related cataracts, and progressive retinal disease (including PRA), causing tearing, corneal changes, lens opacity and gradual vision loss. Early diagnosis—Schirmer tear test, ophthalmic exam and retinal imaging—and prompt treatment (topical cyclosporine for KCS, cataract surgery when appropriate, ophthalmology referral) preserves comfort and vision.
Patellar Luxation & Joint Health in Senior Cavalier King Charles Spaniels — Senior Cavalier King Charles Spaniels commonly develop medial patellar luxation and progressive osteoarthritis. Clinical signs include intermittent hindlimb skipping, lameness, muscle atrophy and pain. Management combines weight control, low‑impact exercise, physical therapy, omega‑3–rich diet or joint supplements, and NSAIDs for pain; surgical correction is recommended for persistent or high‑grade luxations. Regular veterinary exams and radiographs guide prognosis and treatment.
Managing Congestive Heart Failure in Cavalier King Charles Spaniels: Daily Care & Medication Guide — Cavalier King Charles Spaniels are highly predisposed to early-onset myxomatous mitral valve disease, the leading cause of congestive heart failure in the breed. Daily care includes resting respiratory rate and weight monitoring, sodium-restricted feeding, controlled exercise, and regular veterinary/cardiology follow‑ups. Medical management commonly uses furosemide for congestion, pimobendan, ACE inhibitors and adjunctive spironolactone or antiarrhythmics as indicated. ([academic.oup.com](https://academic.oup.com/jvim/article/33/3/1127/8448111?utm_source=openai))
Macrothrombocytopenia in Cavalier King Charles Spaniels: Understanding This Breed-Specific Blood Condition — Macrothrombocytopenia in Cavalier King Charles Spaniels is a heritable, breed‑specific platelet disorder marked by persistently low platelet counts composed of abnormally large platelets. Affected dogs are often clinically normal with minimal bleeding because platelets are usually functionally adequate. Diagnosis is by CBC and blood smear (macroplatelets); distinguishing this benign condition from immune‑mediated thrombocytopenia prevents unnecessary immunosuppressive treatment.
Hip Dysplasia in Cavalier King Charles Spaniels: Diagnosis, Management & Quality of Life — Cavalier King Charles Spaniels can develop hip dysplasia diagnosed by orthopedic exam and radiographs (OFA/PennHIP to assess laxity). Management is multimodal: weight control, NSAIDs, joint supplements, physical rehabilitation, and surgical options (TPO or total hip replacement) for severe disease. Because Cavaliers often have MMVD and syringomyelia, pre‑operative cardiac and neurologic evaluation is essential. With tailored care, many maintain good quality of life.

Nutrition

Senior Cavalier King Charles Spaniel Nutrition: Feeding Guidelines for Dogs 7+ Years — At 7+ years, Cavaliers need a senior diet that maintains lean muscle with high-quality, digestible protein, reduced calorie density to prevent obesity, and added EPA/DHA for joint and cardiac support. Moderate sodium and manage phosphorus if heart or renal disease are present. Include antioxidants, fiber for digestion, and dental-friendly kibble. Monitor body condition and adjust portions with veterinary guidance.
Heart-Healthy Diet for Cavalier King Charles Spaniels with MVD: Sodium, Taurine & Omega-3s — Cavalier King Charles Spaniels with MVD benefit from a heart-focused diet: modest sodium restriction once disease is hemodynamically relevant; test whole-blood/plasma taurine and supplement only if deficient or if a DCM phenotype is present; and consider EPA/DHA (fish‑oil) supplementation or a fish‑oil–enriched diet to reduce inflammation and support cardiac function. Work with your veterinarian or a veterinary nutritionist/cardiologist for dosing and monitoring. ([pmc.ncbi.nlm.nih.gov](https://pmc.ncbi.nlm.nih.gov/articles/PMC6524084/?utm_source=openai))

Food Sensitivities & Allergies in Cavalier King Charles Spaniels: Identification & Dietary Management — Cavalier King Charles Spaniels commonly show food‑related skin disease with pruritus, recurrent otitis, facial/ear dermatitis and occasional vomiting/diarrhea. Diagnosis requires an 8–12‑week elimination diet using a novel‑ingredient or hydrolyzed protein, followed by controlled re‑challenge. Management includes strict lifelong avoidance of identified triggers, limited‑ingredient or prescription hydrolysate diets, treating secondary infections, and EPA/DHA supplementation under veterinary guidance.

Mobility

Safe Exercise for Cavalier King Charles Spaniels with Heart Disease: Activity Guidelines by MVD Stage — Cavalier King Charles Spaniels — ACVIM stage A: normal activity. B1: continue regular low–moderate exercise; avoid prolonged high-intensity sessions. B2: limit to moderate, controlled activity (short brisk walks), watch for cough or fatigue; consult your vet for a tailored plan. Stage C: gentle, short leash walks only; rest frequently and follow cardiac meds. Stage D: minimal supervised activity; seek cardiology guidance immediately.

Cognitive

Mental Stimulation & Cognitive Health for Senior Cavalier King Charles Spaniels — Senior Cavalier King Charles Spaniels benefit from short, daily cognitive enrichment: 10–15 minute training sessions, food-dispensing puzzle toys, scent work, gentle nose games, and predictable novelty. Maintain regular low-impact exercise, social interaction, and consistent routines. Monitor for canine cognitive dysfunction, hearing/vision decline, mitral valve disease, or syringomyelia and schedule veterinary checks every 6–12 months.

End Of Life

End of Life Care for Cavalier King Charles Spaniels: Palliative Options, Hospice & Making the Final Decision — Cavalier King Charles Spaniels commonly develop myxomatous mitral valve disease and syringomyelia. Palliative options include medical management of heart failure (diuretics, ACE inhibitors, pimobendan), multimodal pain control (gabapentin, NSAIDs, opioids as needed), nutritional and mobility support, and hospice-based quality-of-life monitoring. Shared decision-making with your veterinarian determines when suffering justifies euthanasia or hospice-supported natural death.

Frequently Asked Questions About Senior Cavalier King Charles Spaniel Health

At what age is a Cavalier King Charles Spaniel considered senior?

Cavalier King Charles Spaniels are generally considered senior at age 7-8 years. However, due to their extreme predisposition to mitral valve disease (MVD), cardiac screening should begin from age 1 with annual auscultation, and echocardiograms should be performed regularly from age 3-5. Their average lifespan is 9-12 years (VetCompass median: 10.7 years).

What is the most common health problem in Cavalier King Charles Spaniels?

Mitral Valve Disease (MVD) is by far the most significant health concern, with lifetime prevalence approaching 100%. It is 20 times more prevalent in Cavaliers than other breeds and is the leading cause of death. About 50% develop detectable murmurs by age 5, and nearly all are affected by age 10. The EPIC trial demonstrated that starting pimobendan at Stage B2 (heart enlargement) delays congestive heart failure by approximately 15 months.

What is syringomyelia and why are Cavaliers prone to it?

Syringomyelia (SM) occurs when fluid-filled cavities form in the spinal cord due to obstruction of cerebrospinal fluid flow. Over 90% of Cavaliers have Chiari-like malformation (CM) — where the skull is too small for the brain — which predisposes them to SM. About 41% of screened Cavaliers have syringomyelia. Signs include phantom scratching (scratching at the air near the ear/shoulder), neck pain, and sensitivity to touch.

How long do Cavalier King Charles Spaniels typically live?

The average Cavalier lifespan is 9-12 years, with a VetCompass median of 10.7 years. This is somewhat shorter than other breeds of similar size, primarily due to the high prevalence of cardiac disease. Factors that maximize lifespan include early cardiac screening, timely medication (pimobendan at Stage B2), weight management, regular exercise appropriate to cardiac status, and proactive management of syringomyelia if present.

What is PSOM in Cavaliers?

PSOM (Primary Secretory Otitis Media), also called "glue ear," is a condition virtually unique to Cavalier King Charles Spaniels affecting up to 50% of the breed. A viscous mucus plug fills the middle ear cavity, causing pain, head tilting, scratching at ears, and facial nerve paralysis. It is frequently misdiagnosed as syringomyelia because symptoms overlap. Diagnosis requires CT/MRI or myringotomy, and treatment involves flushing the middle ear under anesthesia.
