i am playing fable three for 360 and in brightwall and my dog will not follow me?

[laurafrankyy87]

i follow the golden trail and i have multiple missions from civilians to where i need to dig in brightwall but everytime i get close to following to the point i need to be the dog wont follow and i cant dig. if i run up really fast it will say dig for a second but goes away cuz my dog is nowhere to be seen he is far away chasing his damn tail.
does anyone know how to change this?
