Hello. I am sorry that Bella is unwell. This sounds serious enough that I would really encourage you to have her examined as soon as possible. Coughing & heavy breathing can be a sign of infection from bacterial or fungal sources ( pneumonia ), inflammation from chronic bronchitis, heartworm disease, or cancer. I hope you can have her seen soon so the appropriate treatment can be started. The longer you wait, the more potential for permanent lung damage to occur. Thanks for using Petco Pet Education Center, formerly Petcoach.
