Why do dogs cough and choke? - briefly
Dogs may cough or choke due to various reasons such as irritants in the throat, allergies, or respiratory infections. Additionally, certain breeds with elongated soft palates can experience reverse sneezing, which appears as choking but is typically harmless.
Why do dogs cough and choke? - in detail
Dogs, like humans, can experience coughing and choking due to various reasons. While these episodes may be alarming for pet owners, understanding the underlying causes can help provide appropriate care.
One of the most common reasons for dogs to cough is due to respiratory infections. Bacterial or viral infections can inflame the trachea and bronchi, leading to a persistent, dry cough. Kennel cough, also known as infectious tracheobronchitis, is a prime example of this condition. It is highly contagious among dogs and is often characterized by a honking cough that may progress to gagging or retching.
Another significant cause of coughing in dogs is heart disease. When the heart fails to pump blood efficiently, fluid can accumulate in the lungs, leading to a condition known as pulmonary edema. This results in coughing, often accompanied by difficulty breathing and lethargy. Heartworm disease, which is transmitted through mosquito bites, can also cause severe coughing and respiratory distress as the worms block blood flow within the heart and lungs.
Foreign bodies or allergens can also trigger coughing in dogs. Inhaled irritants such as smoke, dust, or pollen may provoke a coughing response. Additionally, ingested foreign objects that become lodged in the throat or esophagus can cause choking and gagging. This is an emergency situation that requires immediate veterinary attention to prevent obstruction of the airway.
Collapsing trachea is another condition that can lead to coughing in dogs, particularly small breeds. The cartilage rings in the trachea can weaken and flatten, causing partial obstruction of the airway. This condition is often exacerbated by excitement or physical activity and may be accompanied by a honking or goose-like cough.
Lastly, tumors or growths within the respiratory tract can cause persistent coughing in dogs. These growths can obstruct the airways, leading to difficulty breathing and coughing fits. Early diagnosis and treatment are crucial for managing these conditions effectively.
In summary, dogs may cough and choke due to a variety of reasons including respiratory infections, heart disease, foreign bodies, allergens, collapsing trachea, or tumors. Prompt recognition of the symptoms and consultation with a veterinarian are essential for ensuring appropriate treatment and maintaining the dog's overall health.
