Here's why:
* Age: Older dogs are more susceptible to various health issues, including respiratory problems.
* Sudden Onset: A sudden onset of a hacking cough, especially in a senior dog, could indicate something serious.
* Possible Causes: There are numerous potential causes for coughing in dogs, ranging from minor irritations to more serious conditions like:
* Kennel cough: A highly contagious respiratory infection.
* Tracheal collapse: A condition where the windpipe collapses, making breathing difficult.
* Heartworm disease: A parasitic infection that can damage the heart and lungs.
* Pneumonia: An infection of the lungs.
* Allergies: Environmental allergens can trigger coughing.
What to do:
1. Contact your veterinarian immediately. Describe the cough in detail, including frequency, severity, and any other symptoms.
2. Be prepared to provide information: This includes your dog's age, breed, vaccination history, and any medications they are currently taking.
3. Follow your vet's advice: They will likely recommend an exam, tests (such as bloodwork or chest x-rays), and potentially treatment options.
It's important to act quickly to ensure your dog receives prompt and appropriate care. Please don't hesitate to contact your vet.
