Golden retriever aged 6 months. He has been a bit of a challenge, but things were really turning a corner: sleeping through the night, perfectly housetrained, responding very well to a wide range of commands.
But - about two weeks ago he started pulling on the lead - really pulling so that he won't walk on a loose lead for even two seconds. And in the last few days he has started leaping at the lead, becoming very agitated and angry and biting at me to wrench it away. He is quite big and very strong and I just can't manage him. Yesterday he just lay down on the pavement and we had stalemate for ten minutes. No treat will tempt him, no cajouling, angry voice, ignoring - nothing.
He has also started jumping up at passers by, which he never did before. As I said, he is so strong that it takes all my might to hold him back. I have been taking him out at 6.30am to try to avoid pedestrians. He's not too bothered about other dogs - just wants to leap on people.
I have employed all the training techniques recommended for loose lead walking - stopping if he pulls, turning round and walking the other way, etc. I am attending Kennel Club training classes but dog is by far the worst dog there and I'm just getting demoralised.
This morning we didn't even get to the end of the drive as he tried to yank the lead away and went absolutely berserk and knocked me over.
So now I daren't take him out. I just can't think how to move forward.
