Veterinarians have increasingly diagnosed a serious respiratory system pathology called bronchial asthma among four-legged pets in recent years. The current disease develops as the small bronchi inflammation result for various reasons including from congenital anomalies to infectious complications. Treatment should be complex with the mandatory care and feeding improvement. Emergency care is to relieve the acute attack phase.
Dogs asthma causes
The respiratory system pathology may be either congenital and or acquired. Veterinarians identify the following main disease causes based on large medical practice background:
Genetic predisposition. Genetics greatly affects the current disease likelihood. The pets percentage who will suffer from such disorder is high if having the parents’ offspring with such a diagnosis, according to highly-experienced dog breeders.
Various origins allergens, including dust, feed additives, plant pollen, drugs, household toxic chemicals, tobacco smoke, most often become the bronchial asthma cause, according to veterinarians.
Allergens result in small bronchi irritation and hyperemia, which results in dogs pathology development.
Bronchial asthma is often the chronic bronchitis result. The bronchial mucus causes both the tissues irritation and swelling, accompanied by typical ailment symptoms.
Respiratory system infectious diseases. Viruses, bacteria, fungi which provoke pneumonia, bronchopneumonia, laryngitis, tracheitis and bronchitis in pets, cause the small bronchi alveolar tissue intoxication, increase hyperemia, edema and inflammation.
Rather often stressful situations become the dog asthma cause. Both fear and emotional experiences trigger defensive mechanisms in the pet’s body, consisting in enhanced hormone-like substances production. The current phenomenon results in the heart palpitations, hypoxia development as well as clinical disease manifestation.
Unsatisfactory pet care conditions including damp, cold, polluted rooms with drafts increase the current disease development risk in weakened pets.
Physical activity, not corresponding to the dog’s physiological state or age. Both intensive training regime and hard physical work provoke oxygen starvation and normal gas exchange disruption in the body.
Veterinarians and experienced dog breeders note a breed predisposition to the disease. Poodles, pugs and caudate Maltese lap dogs group representatives have an increased risk of such disease development, according to the experts.
Disease signs and symptoms
The characteristic disease symptoms in four-legged pets will not go unnoticed by the owner. The pathology’s clinical picture has certain development stages. The precursors, the attack height of as well as the reverse pathology course stages are distinguished in the asthma pathogenesis. The precursors stage is characterized by the following symptoms:
Breathing nature change. The dog starts to puff and breathe with an open mouth. Breathing whistling is a characteristic bronchial attack initial phase symptom. The dog exhales the air easily but inhales hard. Breath often becomes convulsive and heavy.
Dry strained whistling cough.
Nasal transparent and viscous discharge as well as eye one.
Eye and nose itching. The dog scratches irritation place with its paws.
Wheezing and gurgling breathing sounds may also be observed in a sick pet.
The pet avoids active physical activity and doesn’t participate in games. A walk becomes difficult for a pet.
Reduced appetite and increased thirst.
Bronchial attack increase is the most severe and dangerous disease phase which implies the following clinical picture:
The pet sits or stands with its front paws wide apart and the neck stretched. Its back is hunched, the ribs are straightened. The chest skin is tight.
Such a forced posture is since the pet is trying to compensate for the oxygen starvation by the chest volume increase.
Breathing becomes heavy and intermittent. The inhale is short, whistling and wheezing. The exhale is slow. Convulsive abdomen movements are also observed while breathing. Difficult pet’s breathing becomes noticeable even when the owner is standing certain distance from it. The wings of the nose are dilated, moist.
Abdominal cramps often result in involuntary urination.
The mucous membranes become blue, which means the hypoxia development and is a life-threatening pet’s symptom.
The reverse asthma stage is characterized by characteristic clinical signs attenuation. The pet remains sluggish, apathetic, weak for a long time and has a loss of appetite.
State diagnostic methods
It’s quite difficult to diagnose the current disease due to certain causes and factors existence which provoke it, as well as the need to exclude various similar respiratory organs symptoms. Be sure to make complete clinical examination if suspecting bronchial asthma in your four-legged friend.
Anamnestic data collection is rather important, especially in the event of allergic asthma nature. Auscultation provides an opportunity to identify the inflammatory focus, localization as well as evaluate the lungs and bronchi work.
X-ray chest examination is prescribed to detect pathological changes in pet. The bronchoscopy use provides an opportunity to visualize the bronchi inflammation process as well as to identify alveolar tissue hyperemia and edema areas. Respiratory organs swabs are the most effective diagnosis method which provides full disease clinical picture.
Prediction for pet
Both disease cause elucidation and elimination as well as adequate therapy provide an opportunity to both stop bronchial asthma attack as well as significantly reduce the exacerbations frequency. However, it is impossible to completely eliminate the disease attacks in the event of a genetic predisposition, but not the allergic disease nature.
The prognosis for a pet, suffering from bronchial asthma, is favorable, provided that the owner takes all possible measures to stop an acute attack.
Bronchial asthma is a common respiratory system pathology, most often caused by an allergic cause or developing in chronic bronchitis complication result. The diagnosis complexity is caused by the disease characteristic symptoms which appear during exacerbation period only.
A full clinical examination contributes to true disease cause identification. The treatment is complex. The owner should pay a special attention to help the sick pet during an asthma attack.
