My chihuahua has a dry cough and labored breathing. What's wrong?

Updated on September 23rd, 2025

Pet's info: Dog | Chihuahua | Female | unspayed | 9 years old | 4 lbs

My 4 lbs chihuahua has a cough sometimes and her breathing is a little labored. When she coughs it’s a dry, hacking cough and on occasion produces mucus. Her energy is ok as well as her appetite. Any idea what could be going on? - Julie

Lola is very cute! Her symptoms could be a sign of heart disease, which can be common in older dogs. They could also be caused by allergies or a respiratory disease. The only way to know for sure what is causing her symptoms is to have her seen by a vet. The vet can diagnose what is causing them, and what treatment options are available to her. I recommend calling the vet today to make an appointment for her next week. Best of luck.
