Hi everyone! I have a question. In the last month or two Bonnie has been playing in a 'new' way. She runs at the playmate, biting softly, then suddenly turns quickly presenting her butt to them. I don't do anything, and the playmate does not care. They just keep on keeping on! I am asking because she is going to be spayed next Monday. Is this a sexual behavior? She is 6.6 months old. She also has some adult teeth coming in and the puppy ones are still there. Those will be pulled.
