It looks like a Chuckit erratic ball, but those say Chuckit on them. Maybe an off brand. Anyway it probably was sold as a dog toy.This is the toy. I can't figure out what it is called or who makes it. I did a reverse image search and ended up with results ranging from saxophone mouthpieces to adult toys. Does anyone recognize it? It's about the size of a golf ball. View attachment 355630
