Hello and thanks for using Petco Pet Education Center, formerly Petcoach! It's not possible to say for sure what you are feeling on Jack with just a description and picture. You could be describing a fatty tumor known as a lipoma or another type of mass. Lipomas are benign and I usually don't recommend removing them unless they are causing a problem. Ultimately, to get a diagnosis you'll need to take Jack to your veterinarian. They can take a small needle sample of cells from the location and let you know if it is a lipoma of not.
