I also tried throwing peebles on the ground when he acts, worked some times, and I had to hold the peebles in my hands and show him, so he wouldn't bark to the next byke.

This week I put some coins in an empty beer can which I throw on the ground or shake, and it is working better than the other things I tried; when he sees a byke coming, he looks at me, and I show him or shake the can, he behaves well, he gets a praise or a treat.

He already left a couple of bykes ride by in peace! I hope he will relearn how to behave toward bykes.

It is so unpleasant when he barks at the bykes and the bykers call him names and curse him, I take it to my heart, and feel offended myself, and I feel ashamed for his misbehavior.

I talked to his obedience instructor about this, he said that I should yell NO, ok i did, it didn't work.

Have a nice day.
