I don't have a problem with that in fact I find it a good idea.

I personally find it comforting that other dog owners should be made to keep there dogs on a lead and under control...

I am a rottie owner and I find it offence that people allow there dogs to run free.

If my dog is on his lead and someone elses dog comes running over I personally am not going to allow my dog to get injured so I wont be holding on to no lead.

I can say that on quite a number of occasions I have had to shout @ someone for there dog running free and in the general direct of mine.

and god help the person who's dog may get caught by mine and let them start on with the dangerous dog line --- I'll go to town........
