Well I think the last few posts, like Hazel's are right. Holly is still very young and it's a scary world out there. Just give her time.
When I brought our two 9 week old Malamutes home one was okay with walks the other wanted nothing to do with it. Not a problem now!
If you have a yard and can just get her to play and follow you around in the yard for a bit in time the walks will come. Treats worked great with us also.
With the larger dogs it was recommended to me 5 minutes of walking for every month old they are. At 8 months now we just go where ever we want.
Patience will be key with Holly. Continue with the carry to the corner and walk her back if you must, but she will get the hang of it eventually.
