There are many possible reasons why your dog might be coughing at night, and some of them could be serious. A vet can diagnose the cause and recommend the appropriate treatment.
Here are some things a veterinarian might consider:
* Kennel cough: A highly contagious respiratory infection that can cause coughing, especially at night.
* Allergies: Allergies to dust mites, pollen, or other allergens can trigger coughing, particularly at night when your dog is resting.
* Heartworms: This parasitic infection can cause coughing, particularly at night when your dog is lying down.
* Tracheal collapse: A condition where the trachea (windpipe) collapses, causing coughing, especially when your dog is excited or lying down.
* Other respiratory infections: Bacterial or viral infections can cause coughing, especially at night.
Please don't hesitate to contact your veterinarian to get your dog the proper care.
