Hey! Just had a question about my dog. Randomly starting yesterday evening and now into the morning my dog’s had a loud cough and gag after but is still being his normal hyper self. It seems to be happening after he gets excited though. Once he settles down and relaxes, the coughing goes away. He’s still eating and drinking fine and he slept fine. He didn’t get into anything either that would’ve gotten stuck in his throat.

Thank you for submitting your question! There are two scenarios that come to mind with a small breed dog that develops a cough. The first is an upper respiratory infection. This will cause a hacking or gagging cough that can produce a white foamy material. The second is a condition known as collapsing trachea. In this case, the trachea (wind pipe) weakens and loses its shape. This results in a honking cough in the dog. Your veterinarian will be able to differentiate between the two and decide if treatment is warranted. I hope this information helps!
