Must be certain lines. Was kinda funny...I had been talking to a friend of mine that has Vizsla's, who helped me evaluate a Lab litter, and I was explaining Bolo spots to them. She was telling me about Futaki horns in Vizsla's and a few weeks later I noticed them on my Lab puppy! lol Been in labs for 15 years and had never seen them on a Lab before. Pedigree was an outcross. No big deal...just surprised me and wondered how common they were in Labs.

Yes, all the time
How ironic! I have a new puppy that has one on each ear just like the picture, and one on the inner ear. First time I have ever seen them too!
