Thank you for using Petco Pet Education Center, formerly Petcoach. I would recommend taking Jack into the veterinarian to have his lump and cough assessed. The two may be unrelated issues, or it is possible that the lump is related to the cough. The vet may recommend aspirating or biopsying the lump to determine what it is, taking xrays to look at his heart and lungs or other diagnostics.
