I have cockers and they are prone to getting warty type growths on them. They seem to develop in the latter years.
Some of the benign things you can just let go, unless they develop into a problem. Had a few dogs have some, that grew larger when they were older, and they would knock them open and they'd bleed. We pretty much just let them go unless they start bleeding or turn into a problem. If that happens we remove them.
I'd get it checked by a vet. It could be nothing, but it could be something.
I'm not familiar with your breed, so I don't know if it's common or not.
Good luck.
