Thanks for using Petco Pet Education Center, formerly Petcoach! Open mouth breathing can be a sign of many conditions such as pneumonia, bronchitis, heart disease, among many other possibilities. I recommend that you have Bruce evaluated by a veterinarian for further assessment and treatment. Likely diagnostics to be performed include thoracic radiographs and bloodwork. Treatment would be dependent on findings. Good luck and have a good night!
