Thank you, Jawjaw. Think Magnum called him Higgy sometimes; that's what I remember. After I posted that post, I did remember the Higgins version.

Chatty,
I think that's cool; you adopted and bought Dobermans due to
the suggestive power of the PI show. I really think miniature Dobermans are really neat. Never owned a Doberman but they sure are nice! Both of us had a dog named Shadow! I still miss my Shadow and Cherrie and Casey and Pepper and Buddy and Nicky and Penny: Those were dogs I have lived with over the years that went to be with The Lord. Each one has a special place in my heart!
