Getting an 8 month old dog use to a leash?

I might drive her to another area where she isn't as comfortable and see if she doesn't behave a little better. My corgi did the plop down, wet rag impression for a long time. He would heel perfectly, but he hated the collar and leash. It was so pathetic.

When we took our puppy to obedience class, we started with a short leash and a harness, and worked up to a longer leash with a collar.

have you tried a harness with a leash? I did that with mine to start as well. It gives you more control and keeps them secure and safe. You can attach the leash to it. Here's a different brand but mine have the Kong one. It has a padding in the front and keeps them from pulling. Duke gets all excited when I get it out. No Pull DogHarness. Then we attatch the extended leash to it so I can give them more or less leash depending on how their doing or how much they want to run.

Yet another vote here for a harness. Somehow it seems less "confining" or something. Our dog was 9 months when we got her from the shelter and she was also the "flop and roll" kind. lolol.  I felt like I was torturing her with the collar. Also, she was a Houdini so it was safer to put her in a harness. We got the kind where the leash attaches in front on the dog's chest, so if they pull it "pushes" them there and slows them down. That's the theory anyway. 

I had her wear the harness around the house, then I attached a leash to that and made her come around the house with me. Come to think of it, maybe I have only myself to blame for the fact that she's now my shadow. I can't even go in the bathroom without having her nose come around the door. 

Yes, we never, ever use collars anymore; only harnesses. I highly recommend the Easy Walk Harness and a short leash around the house and out to go potty on a longer leash if needed. We always use a 6 foot leash for walks and outside.

Walks will come. It will take time but taking it slow and easy is best. Puppy is getting used to the new house, etc. Enjoy, and do you have a photo?

We had a devil of a time with our rescued Lab, who was 2, at first. She would go berserk on a leash. We tried the gentle leader and she went so nuts I thought she would kill herself. So, we walked her late at night, with the leash on trailing but not holding it. Now this only worked because she was like glue to us, and would not run away, but would pull and go nuts if the leash was held but would follow us fine on a walk. Midnight, no lie, in case people or dogs were out we would walk! After while she got slowly better and better, and eventually the gentle leader was a go and it worked great umtil we no longer needed that and she "got" walking. Yes, she was a bit of a basket case, lol.
