Hi and thank you for your question! If there is a cutaneous mass on one side of his abdomen, this can make it look as if his stomach is growing larger on one side. Sometimes these are fatty tumors which can grow quite large. If you can submit a picture, that could help. Thank you for using Petco Pet Education Center, formerly Petcoach!
