Don't know why, and I'm not concerned about it, but just think it's a bit
different.
I've never had a dog before that doesn't do any toileting on a walk.
In fact most of my previous dogs have pee-d on nearly everything they can on
a walk, but not this one.

Is this unusual?
He's an 18 month old, German wire-haired pointer (Mum), and
Ridgeback/Rottweiler (Dad), cross.
(He's Caspian, the dog I mentioned here a year or so ago that we rescued
from a drug-addict that was mistreating him)
