I am taking our puppy out for a few experimental walks to the end of the road and at first he seemed very keen and into it, but tonight he point blank refused to move!

I have tried every trick I can think of, when I offer him a treat he moves forward to eat it, then sits back down again. I also just stood completely still with my back turned to him but he wasn't playing ball. On the few occasions he did walk I gave him lots and lots of praise but he still only took a few paces forward. I have attempted to 'transmit' my calm assertive energy down the lead but he just looked at me like I was a fool!

I have been really looking forward to walking him and am feeling a little disheartened, does anyone have any advice?
