Respiratory Diseases

    1.     Aspiration Pneumonia (Foreign-body pneumonia, Inhalation pneumonia, Gangrenous pneumonia)

Aspiration pneumonia is a pulmonary infection characterized by inflammation and necrosis caused by inhalation of foreign material. For more information click here or call your veterinarian.

    2.     Chlamydial Pneumonia

Chlamydiae have been identified in various parts of the world as a cause of enzootic pneumonia in cats. The main clinical sign of zoonotic chlamydiosis in humans is pneumonia, generally contracted from pet birds. For more information click here or call your veterinarian.

    3.     Diaphragmatic Hernia

A break in the continuity of the diaphragm allows protrusion of abdominal viscera into the thorax. For more information click here or call your veterinarian.

    4.     Hypostatic Pneumonia

Hypostatic pneumonia is caused by passive or dependent congestion of the lungs, a condition most commonly seen in older or debilitated animals. For more information click here or call your veterinarian.

    5.     Laryngeal Disorders

    1. A.     Laryngitis

Laryngitis, an inflammation of the mucosa or cartilages of the larynx, may result from upper respiratory tract infection or by direct irritation from inhalation of dust, smoke, or irritating gas; foreign bodies; or the trauma of intubation, excess vocalization, or in livestock, by injury from roping or restraint devices. For more information click here or call your veterinarian.

    1. B.      Edema

Edema of the mucosa and submucosa is often an integral part of laryngitis and, if severe, the rima glottidis may be obstructed. For more information click here or call your veterinarian.

    1. C.     Laryngeal chondropathy

Laryngeal chondropathy is a suppurative condition of the cartilage matrix that principally affects the arytenoid cartilages; it is believed to result from microbial infection, often as a sequela of inhalation of irritants. For more information click here or call your veterinarian.

    6.     Lungworm Infection (Verminous bronchitis, Verminous pneumonia)

An infection of the lower respiratory tract, usually resulting in bronchitis or pneumonia, can be caused by any of several parasitic nematodes in dogs and cats. For more information click here or call your veterinarian.

    7.     Mycotic Pneumonia

Fungal infection of the lung results in an acute to chronic active, pyogranulomatous pneumonia. For more information click here or call your veterinarian.

    8.     Pharyngitis

Pharyngitis is an inflammation of the walls of the pharynx. It may accompany most upper airway viral and bacterial respiratory infections, eg, distemper in dogs. For more information click here or call your veterinarian.

    9.     Pulmonary Emphysema

Alveolar emphysema is abnormal permanent enlargement of air spaces distal to the terminal bronchiole and destruction of alveolar septal walls without apparent fibrosis. Interstitial emphysema is the presence of air within the supporting connective tissue stroma of the lung. For more information click here or call your veterinarian.

    10. Allergic Pneumonitis 

Allergic pneumonitis is an acute or chronic hypersensitivity reaction of the lungs and small airways. For more information click here or call your veterinarian.

    11. Canine Nasal Mites 

Pneumonyssoides caninum is known as the canine nasal mite. There does not seem to be a breed, age, or sex predilection, although one report suggested that dogs >3 yr of age were affected more often and that large breed dogs had a higher incidence than small breed dogs. For more information click here or call your veterinarian.

    12. Feline Respiratory Disease Complex 

Feline respiratory disease complex includes those illnesses typified by rhinosinusitis, conjunctivitis, lacrimation, salivation, and oral ulcerations. The principal diseases, feline viral rhinotracheitis (FVR) and feline calicivirus (FCV) infections, affect domestic species. Feline infectious peritonitis and pleuritis typically causes a more generalized condition but may cause signs of mild upper respiratory tract infection. Two types of modified live virus FVR-FCV vaccines are available. For more information click here or call your veterinarian.

    13. Lung Flukes 

Paragonimus kellicotti and P westermani usually are found in cysts, primarily in the lungs of dogs and cats. For more information click here or call your veterinarian.

    14. Lung nematodes

A.      Aelurostrongylus abstrusus 

Aelurostrongylus abstrusus is the most common lungworm of cats. They are small parasites, deeply embedded in the lung tissues. For more information click here or call your veterinarian.

B.      Capillaria aerophila 

Although usually parasites of the frontal sinuses, trachea, bronchi, and rarely nasal cavities of foxes, Capillaria aerophila are found in dogs and other carnivores.

C.     Filarids 

Oslerus (Filaroides) osleri are tracheal worms of dogs, usually found in thin-walled nodules around the bronchial bifurcation. Persistent, dry cough is the most common clinical sign. Filaroides hirthi is similar to O osleri but is found in the lung parenchyma. For more information click here or call your veterinarian.

    15. Neoplasia of the Respiratory System

A.     Tumors of the Nose and Paranasal Sinuses

Tumors of the nose and paranasal sinuses account for 1-2% of all canine or feline tumors. The incidence in dogs is twice that in cats; incidence is also higher in males of both species than in females. The mean age at time of diagnosis is 10.5 yr for dogs and 12 yr for cats. For more information click here or call your veterinarian.

    1. B.      Tumors of the Larynx and Trachea 

Tumors of the larynx and trachea are rare in dogs and cats. Tumors of the trachea are particularly rare. For more information click here or call your veterinarian.

    1. C.     Primary Lung Tumors 

Primary lung tumors are rare in dogs and cats; however, the reported incidence of lung carcinomas has increased at least 100% during the last 20 yr. For more information click here or call your veterinarian.

    1. D.     Metastatic Tumors of the Lungs 

A localized tumor may extend to the lungs by dissemination through hematogenous or lymphatic routes or by direct extension of tumor cells. For more information click here or call your veterinarian.

    16. Pneumonia 

Pneumonia is an acute or chronic inflammation of the lungs and bronchi characterized by disturbance in respiration and hypoxemia and complicated by the systemic effects of associated toxins. The usual cause is primary viral infection of the lower respiratory tract. For more information click here or call your veterinarian.

    17. Rhinitis and Sinusitis 

Inflammation of the mucous membranes of the nose and sinuses may be acute or chronic. For more information click here or call your veterinarian.

    18. Tonsillitis 

Tonsillitis is common in dogs but rare in cats. In dogs, it seldom occurs as a primary disease, but when present it is most frequently seen in small breeds. For more information click here or call your veterinarian.

    19. Infectious Tracheobronchitis of Dogs (Kennel cough)

Infectious tracheobronchitis results from inflammation of the upper airways. It is a mild, self-limiting disease but may progress to fatal bronchopneumonia in puppies or to chronic bronchitis in debilitated adult or aged dogs. Dogs should be immunized with modified live virus vaccines against distemper, parainfluenza, and CAV-2, which also provides protection against CAV-1.
