You say he is running behind you when birds get up?? If not,Is it chasing after birds get up? Remember what i said e-mail or so ago, about dog assoc. bang to the birds?? It is something so small being done at the time that turns into something so drastic. Ok have you got access to any pigeons? Let me know and we'll get the booger worked out. Sounds like it won't be to awful bad. Jonesy
