He is sensitive to sound.. skateboard noise scares him (not surprised), shreeky voices outside when walking etc. etc.. no raising voice needed ( hurtful).. just a normal 'no' when there should be something,
I would not want him to do ( forget, if there was ?) and then, to make him aware so he is safe. and he
will get it right away. Love his movement while walking him on the lead (NEVER off lead outside;;once this kind of dog starts running (things that move very inviting to chase ..).. 3 steps to 40mph-- might be his last.. cars can in most cases not stop fast enough.. because of Greyhound
speed.. would see him too late.. When on lead.. things are 'cool'..
