If your dog suddenly develops a harsh, honking cough that sounds like they’re trying to clear something stuck in their throat, you’re likely dealing with kennel cough.

Most cases of kennel cough are mild and self-limiting, resolving on their own within 10-21 days. However, understanding what causes kennel cough, recognizing when your dog needs veterinary care, and knowing how to support their recovery can make a significant difference in their comfort and healing timeline.
