I walked our Female 6 month old lab (Luna) for 40 minutes, then took her swimming. She did 5 long fetches. When I got home all she did was chase flying insects and moths in the back yard. I sat outside with her for and hour and I could not redirect her. I then grabbed some treats and called her. She was more interested in the bugs than coming to me. She has chased flies in the past but not to this extent. Should I worry about this?
