I noticed a bald spot on Kaners tail. Its right at the first "ball shaped" portion of his tail. I guess its right after what would be the stump? My cousin says that the ball shaped (not sure what its called... spine?) is too big. He told me to squeeze it but Kaners like 65 pounds right now and i don't know if im brave enough to squeeze anything on him

.
Ive only ever seen bald spots on dogs who are caged a lot and its usually their elbows. Any idea why this is happening and how to stop it? Anyone think my cousins squeeze advice is good advice?
These are the best pics i could get because Kaner is too wiggly. Its right on the bottom of the tail.
