Apparently the dog from the Prospect Park bench talks about me at home

A large and very confident dog walked up to me on a bench in Prospect Park one Sunday morning and put his chin on my knee like we had agreed on it. The owner apologised four times. We sat there for an hour. The dog never moved. Now the three of us walk the same loop every Sunday and the owner says the dog talks about me at home. I do not ask what he says. I think it is mostly about my knee.
