Collapsed Trachea in Maltese: Causes, Signs & Treatment

Maltese are a beloved toy breed with a long, affectionate history. Their small size, dainty build, and white coat often make them appear fragile — and as they enter their senior years (commonly around 8–9 years old, lifespan ~12–15 years), several breed-predisposed problems can emerge. One respiratory condition that commonly affects small and toy breeds, including Maltese, is tracheal collapse. This article explains what tracheal collapse is, why Maltese are at risk, how to recognize it, how veterinarians diagnose and treat it, and what owners of senior Maltese should do at home and with their veterinary team.

What is tracheal collapse?

Tracheal collapse is a dynamic narrowing of the tracheal lumen caused by weakening and flattening of the tracheal rings (cartilage) and/or redundancy of the dorsal tracheal membrane. The collapse may occur in the cervical trachea (neck), intrathoracic trachea (chest), or both. When the airway narrows, air flow is restricted and turbulence produces the characteristic chronic "honking" cough. In severe cases, dogs may experience respiratory distress, cyanosis, or collapse.

Anatomic and histologic changes include chondromalacia (softening or degeneration of tracheal cartilage) and changes in connective tissue of the tracheal membrane. The disorder is most often progressive and is classically reported in small and toy breeds — Yorkshire Terriers, Pomeranians, Chihuahuas, Poodles, and Maltese are over-represented in clinical series.

(For a veterinary review of clinical features and treatment options, see standard texts such as Fossum: Small Animal Surgery and review articles in the Journal of Small Animal Practice and Journal of the American Veterinary Medical Association.)

Why are Maltese predisposed?

Breed-specific reasons include:

• Small tracheal diameter: toy breeds have narrower tracheas that are more sensitive to partial obstruction.
• Genetic and developmental tendencies toward weaker tracheal cartilage in toy breeds.
• Conformation: short necks and certain chest conformations can alter intrathoracic pressures.
• Comorbidities common in Maltese seniors — especially chronic [dental disease](https://seniorpet.org/knowledge/siamese-cat-dental-disease "Dental Disease in Senior Pets"), chronic bronchitis, and degenerative [mitral valve disease](https://seniorpet.org/knowledge/cavalier-king-charles-spaniel-mitral-valve-disease "Mitral Valve Disease Guide") (MVD) — can exacerbate coughing or mimic tracheal collapse.

Maltese also frequently present with other senior conditions (luxating patella, cataracts, portosystemic shunting in young dogs, white shaker syndrome, and dental disease) that affect anesthesia planning, drug metabolism, and overall prognosis. Cardiac disease (MVD) deserves particular attention because coughing and exercise intolerance from MVD can be mistaken for or occur alongside tracheal collapse.

Typical age of onset in Maltese

Although tracheal collapse can appear in middle-aged dogs, clinical signs commonly become more evident in older small-breed dogs. For Maltese, owners and veterinarians should be vigilant from about 6–8 years of age onward, with many clinical cases presenting at 8–10 years.

Signs and clinical presentation

Typical signs in a senior Maltese include:

• A persistent, dry, "goose-honk" cough especially when excited, pulling on a collar, or during exercise.
• Episodes of retching or “gagging” after coughing.
• Increased coughing with pressure on the trachea (neck) or during excitement.
• Exercise intolerance and fast fatigue.
• Inspiratory or expiratory noise that varies with location of collapse:

- Cervical tracheal collapse often produces an inspiratory honking cough. - Intrathoracic collapse more often causes expiratory difficulty and may be worse during exercise.

• Severe cases: cyanosis, collapse, or labored breathing — this is an emergency.

Because Maltese are also predisposed to mitral valve disease (MVD), which can cause coughing and exercise intolerance, owners should not assume cough is due to [heart disease](https://seniorpet.org/knowledge/cavalier-king-charles-spaniel-mitral-valve-disease "Heart Disease in Senior Pets") or tracheal collapse alone. A full diagnostic workup is needed.

Diagnostics: how veterinarians confirm tracheal collapse

Veterinarians use a combination of history, physical exam, and imaging/tests:

• Physical exam: palpation may elicit coughing. Auscultation and evaluation for concurrent cardiac murmurs (MVD) or lung disease.
• Thoracic radiographs (plain x-rays): can show tracheal narrowing, but static x-rays may underestimate dynamic collapse. Radiographs are useful to screen for cardiogenic pulmonary edema (MVD) or other lung disease.
• Fluoroscopy: dynamic imaging during respiration that better demonstrates tracheal collapse and the degree of dynamic narrowing.
• Tracheoscopy (bronchoscopy): the gold standard to directly visualize the trachea and airways, and to look for concurrent bronchitis or foreign material.
• Echocardiography: essential in Maltese seniors because of the high prevalence of mitral valve disease; helps differentiate cough due to left-sided heart disease vs airway disease.
• CBC/chemistry and pre-anesthesia testing: especially important given common comorbidities in Maltese (e.g., hepatic shunts in younger dogs, dental disease increasing septic risk; seniors for anesthesia risk).
• Advanced testing: airway culture/bronchoalveolar lavage if infection is suspected.

If a Maltese has signs of respiratory distress, immediate supportive care and imaging should be arranged without delay.

Staging and what it means for treatment

Veterinary clinicians commonly grade tracheal collapse by severity (1–4). This grading helps guide management.

| Grade | Typical radiographic/fluoroscopic finding | Typical clinical management | |-------|-------------------------------------------|-----------------------------| | Grade 1 | Slight flattening of tracheal lumen (<25% narrowing) | Medical management, environmental control, harness use | | Grade 2 | Moderate collapse (25–50% narrowing) | Medical therapy + lifestyle changes; consider referral if refractory | | Grade 3 | Marked collapse (50–75% narrowing) | Aggressive medical management; evaluate for stent/surgery in severe clinical cases | | Grade 4 | Near-complete collapse (>75% narrowing) | Interventional treatment (stent) or palliative care; emergency management if respiratory compromise |

(Adapted from standard veterinary staging approaches used in clinical practice.)

Medical (non-surgical) management

Most Maltese with mild–moderate tracheal collapse are managed medically. Goals are to reduce coughing, inflammation, and lower airway secretions while addressing underlying or contributing conditions.

Common medical strategies:

• Harness-only policy: avoid neck collars; use a well-fitting harness to prevent direct tracheal pressure. This is critical for Maltese due to their small necks.
• Weight control: even small weight loss reduces respiratory workload. Maintain lean body condition.
• Cough suppressants: short-term use of narcotic antitussives such as hydrocodone or butorphanol under veterinary direction. Avoid chronic high-dose opioids without reevaluation.
• Anti-inflammatories: short courses of systemic corticosteroids can reduce inflammation during flare-ups, but long-term steroids are discouraged due to side effects (esp. in geriatric dogs). Inhaled corticosteroids (e.g., fluticasone) may be used for longer-term control with fewer systemic effects.
• Bronchodilators and mucokinetics: drugs such as theophylline or inhaled bronchodilators may be considered in selected cases.
• Antibiotics: only if bacterial infection is documented or strongly suspected (culture/bronchoalveolar lavage or cytology).
• Treat comorbidities: heart medications for MVD (ACE inhibitors, pimobendan, diuretics if indicated) after cardiology assessment; dental disease treatment and regular dental care; control of chronic bronchitis if present.
• Environmental management: minimize exposure to smoke, aerosols, strong perfumes, dust, and cold air — Maltese may be particularly sensitive given small airway caliber.

Medical therapy typically controls clinical signs for many senior Maltese; veterinary follow-up is essential to adjust therapy.

Interventional and surgical options

When medical therapy fails or when a Maltese has severe (grade 3–4) collapse with life-limiting signs, interventional options are considered:

• Extraluminal ring prostheses (surgical rings): permanent rings placed externally around the cervical trachea to restore diameter. Typically best suited for focal cervical collapse and in dogs large enough to tolerate surgery. In toy breeds like Maltese, extraluminal rings are often not feasible for intrathoracic disease and may be technically challenging in very small patients.
• Intraluminal stents (self-expanding metallic stents): placed endoscopically across the area of collapse (cervical, thoracic, or both). Stents can dramatically improve airway patency and [quality of life](https://seniorpet.org/knowledge/siamese-cat-quality-of-life "Quality of Life Assessment") and are frequently used in small breeds. Limitations and complications include stent fracture, migration, excessive granulation tissue, coughing persistence, and potential for airway infection. Long-term follow-up is necessary.
• Tracheal resection and anastomosis: rarely an option and typically not for diffuse collapse.
• Palliative measures: oxygen therapy, controlled activity, and hospice care when interventions are not appropriate.

Referral to a board-certified surgeon or interventionalist experienced with tracheal stenting is recommended for senior Maltese with advanced disease. Discuss expected outcomes and potential complications; many dogs do well for months to years after stenting, but stent-related complications can occur and may require further procedures.

How tracheal collapse interacts with other conditions in Maltese seniors

Maltese often have comorbidities that influence diagnosis and treatment:

• Mitral Valve Disease (MVD): MVD is common in Maltese. Cough from left atrial enlargement or pulmonary edema can mimic tracheal collapse. Echocardiography distinguishes cardiac causes and is essential before major interventions. Some cardiac medications (e.g., diuretics) might exacerbate dehydration or alter drug kinetics.
• Dental disease: Chronic periodontal disease is common in Maltese and can seed bacteria to the lungs or complicate anesthesia. Address dental disease before elective procedures.
• Portosystemic liver shunt (PSS): Often a congenital condition seen in Maltese puppies/young dogs; if present it affects drug metabolism and anesthetic planning. Always screen a Maltese with suspected PSS carefully prior to general anesthesia.
• White shaker syndrome: Immune-mediated central nervous system disease in small white breeds (including Maltese). Its therapy commonly includes high-dose corticosteroids, which can complicate long-term airway inflammation management; coordination between neurologist and primary vet is necessary.
• Luxating patella and cataracts: These orthopedic and ophthalmic issues do not directly affect tracheal collapse but may limit exercise modification plans or anesthesia protocols.

A coordinated approach with internal medicine, cardiology, surgery, dentistry, and anesthesia specialists yields the best outcomes for complex senior Maltese.

Practical, actionable advice for Maltese owners

Harness, not collar: Immediately switch to a comfortable, well-fitting harness to remove pressure from the neck.

Keep vaccinations and dental care current: Regular dental cleaning and good home dental care reduce periodontal disease and potential respiratory seeding.

Manage weight: Aim for ideal body condition; even small excess weight increases breathing work in a toy breed.

Environmental control: Eliminate cigarette smoke exposure, avoid aerosols and strong scents, use a humidifier in dry climates, and avoid sudden cold air exposure.

Monitor and record cough episodes: Note triggers, frequency, timing, and progression. Video recordings of episodes are very useful for veterinarians.

Seek prompt veterinary care for worsening signs: Any cyanosis, open-mouth breathing, collapse, or inability to exercise is an emergency.

Coordinate care: If your Maltese has MVD, PSS, or other comorbidities, ensure the entire veterinary team is aware before starting steroids, anesthetic procedures, or complex interventions.

Ask about inhaled therapy: For long-term control, inhaled corticosteroids and bronchodilators delivered via spacer and mask can reduce systemic effects.

Prepare for diagnostics: Fluoroscopy or tracheoscopy may require sedation or anesthesia; discuss risks given your Maltese’s age and coexisting conditions.

Consider referral early: If cough is progressive despite medical therapy, referral to a veterinary specialist for stenting evaluation can improve outcomes.

When to seek emergency care

Go to an emergency clinic if your Maltese has:

• Difficulty breathing or rapid, shallow breathing
• Blue or grey gums/tongue (cyanosis)
• Collapse or unresponsiveness
• Severe, uncontrolled coughing leading to collapse

These are life-threatening signs requiring immediate oxygen, sedation, and expert airway management.

Expected outcomes and prognosis

Prognosis depends on severity, comorbidities, and treatment chosen:

• Mild (grade 1–2): Good long-term control with medical management and lifestyle changes.
• Moderate to severe (grade 3–4): Medical management may provide temporary improvement; surgical or intraluminal stenting often improves quality of life but carries procedure-related risks. In the presence of advanced MVD or severe systemic disease, prognosis may be guarded.

Multiple veterinary studies and clinical reviews of tracheal stents report improved clinical signs and owner satisfaction, but also highlight the need for long-term follow-up for stent complications (migration, fracture, formation of granuloma tissue). Decisions must be individualized for each Maltese.

Evidence and references

• Tracheal collapse is well-described in small breeds in veterinary literature; dynamic imaging (fluoroscopy) and tracheoscopy are standard for diagnosis (see review articles in Journal of Small Animal Practice and JAVMA).
• Outcomes following intraluminal stenting have been reported in multiple clinical case series showing symptomatic improvement in most dogs, with recognized complication rates that require monitoring (see veterinary surgery and interventional radiology literature).
• Comorbidity considerations (MVD, PSS, dental disease) are emphasized in veterinary cardiology and internal medicine texts; echocardiography is required to evaluate MVD as a cause of cough.

For an in-depth review of airway surgery and stenting techniques, consult standard surgical texts (e.g., Fossum, Small Animal Surgery) and current peer-reviewed articles in specialty journals. Your primary veterinarian or a board-certified veterinary surgeon or cardiologist can provide citations and discuss the most up-to-date evidence relevant to your Maltese.

Follow-up and long-term care

• Routine rechecks: Every 3–6 months or sooner if symptoms change.
• Imaging follow-up: Repeat radiographs, fluoroscopy, or endoscopy as recommended post-intervention.
• Medication review: Senior Maltese often take multiple medications; regular review minimizes adverse interactions, especially with cardiac drugs or when corticosteroids are used.
• Emergency plan: Keep a written plan from your veterinarian about emergency steps and contact numbers.

Final thoughts

Tracheal collapse is a common and treatable cause of chronic cough in senior Maltese. Early recognition, simple lifestyle adjustments (harness use, weight control, environmental changes), and careful coordination with your veterinary team often control symptoms. For progressive disease, interventional options such as intraluminal stenting can offer significant improvement but require referral to experienced specialists and long-term monitoring. Because Maltese have a high incidence of mitral valve disease, dental disease, and other comorbidities, a thorough, individualized diagnostic and therapeutic plan is essential to achieving the best outcome for your senior Maltese.

If you notice a persistent honking cough, exercise intolerance, or episodes of breathing difficulty in your Maltese, record the episodes (video helps) and schedule a prompt veterinary evaluation.
