Hi Petco Pet Education Center! My dog has medium sized lump under his skin, right by his chest and rib cage. Is this something I should be concerned about?

Hello. This is probably a benign neoplasia called a lipoma, but any lump, bump or nodule that pops up, especially on an older dog, should be brought to your veterinarians attention as quickly as possible. Sometimes we will do a very simple needle aspirate to look for any unusual cells under the microscope, or your veterinarian may just elect to watch things. But it should at least be evaluated. Hope all is well & thanks for using Petco Pet Education Center, formerly Petcoach.
