Man of Honour
I always laugh when I see a big dog like that on an extenable lead. I'll let you off though becasue he has the halter neck on. Great for lead training. I can walk mine without restraint more often that not thanks to using a halter when they were younger but they are too excitable so I put them on just in case.
99 times out of 100 he's fine on a lead now. The only problem is his energy and excitability around other dogs. He's overzealous at playtime and some dogs don't like that, especially the older or much smaller dogs, so I can only let him off the lead at certain times.
