2 - if my dog was unsure of you, he was sensing something I initially couldn’t.
Extremely well socialised ‘bomb-proof’ dog. Not easily spooked, took all in his stride.
If he ‘watched’ you, so too did I.
(Was rare but I took notice)
Interaction with other dog owners.
Easy to discuss my special interest with other dog owners covertly.
Get out with dog and do some good,
raising funds for charities (longest sponsored walk to date is 18 miles around all three dams and them some, in Derbyshire, with dog

)
He was fine with my silences. Probably preferred them

A sense of responsibility toward complete strangers.
I was liable for my dogs behaviour in the eyes of the law. No excuses or BS. Black and white responsibility.

3 - Been alive for almost half a century.
4 - greatest dog I ever had the privilege of sharing many years with.
5 - not friendship, Mutual respect. An understanding. Each having a clearly defined role to play.
Easy when one knows the rules and understands the lingo.
