Jesus, seemed to have started something here!
I'd like to think that I am a responsible dog owner – Elaine, my dogs have never humped anything and normally I have them under control and I am the pack leader. As I have said above, I only have this one particular issue. I can take them out on my bike and they follow me, completely ignoring other dogs, bikes etc.
I know that a bit of retraining is required – I was just looking for a few quick pointers from anyone who has experienced similar issues. Looks like its back to the long leash and a firm rebuke. Anybody seen my Koelher Handbook?
