Thanks for using Petco Pet Education Center, formerly Petcoach! Heavy breathing can be a sign of many conditions such as pneumonia, bronchitis, heart disease, among many other possibilities. I recommend that you have Walter evaluated by your 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 day!
