Why is my older dog hacking, wheezing, and trying to throw up?

Updated on September 23rd, 2025

Pet's info: Dog | Jack Russell Terrier | Male | neutered | 13 years and 2 months old | 30 lbs

My dog has been having a hacking/wheezing cough lately. It's not connected to physical activity; he wakes up in the middle of the night coughing. He coughs, and then it seems like he's going to throw something up, but he doesn't. He doesn't spend time around many other dogs, and isn't ever boarded, so I'm not sure if it could even be kennel cough. He's been eating less, but still eating.

I agree that infection is less likely in Chandler if he is to around other animals. At Chandler's age I would be most concerned about heart disease causing his cough. In a Jack Russel terrier a collapsing trachea or even asthma could also be causing these signs. Unfortunately, cancer can also be a cause of coughing in an older dog. I definitely recommend you take Chandler to your veterinarian for an X-ray and examination. If heart disease is present medications can be started to reduce the cough. Thank you for using Petco Pet Education Center, formerly Petcoach and I hope Chandler is feeling better soon!
