Hello!
Sorry, just a quick reply as I'm mid-cook!!
Firstly, have you tried doing the
opposite to what your trainer says - Pick him up and carry him for a while -
then put him down?
Secondly - have you tried walking him in the
opposite direction to what he's used to?
We had a Schnauzer that, if I walked down a 'wrong' road, or turned to go home before 'his usual turning point' - would sit down and refuse to move aaargh!!
Good luck! Sally + Harry
