Hi all - I am new to this dog ownership business, let me confess straightaway, but we are loving our new pup - he is a 12-week-old fawn whippet and has a fabulous temperament, is doing brilliantly with toilet-training, sleeps through the night (after two or three hellish nights of whining/weeping at the beginning!) and is generally an absolute charmer.
The one area we are really struggling with, however, is walking him from the house! He is most reluctant to do this - partly because he doesn't like the cold, I guess, being a shivery little whippet boy - but mainly, I think, because it's leaving his patch? I say this because he is much better when we walk from the car (ie in an area not known to him, eg a new park, a wood, etc). We've tried the advice we've read, such as staying relaxed, not looking at him, just giving the lead a gentle tug and striding forth, encouraging him - sometimes this works, but very often it doesn't. It takes an age just to get out of our cul-de-sac to the main road! He constantly tries to turn around and scurry back home (to the warmth, the kids, his food, etc - who can blame him, in some ways?!)
I have no idea whether I need to worry about this at all, at this early stage - maybe this is common - but I am a walker, and live in town, and am used to striding forth to do my errands, and really hope this is just a temporary blip!
Thanks for any advice. I know he's only young and can only walk short distances anyway right now but any techniques you know about that might be help would be gratefully received 
(I know there is a very helpful pointy dog thread but I decided this was a more general kind of problem, which can presumably apply to any breed!)
