Bruno the Lion Dog, aka Leonberger. Such a wonderful breed .... big, gentle, intelligent & very protective ....apparently their job was to guard the sheep at night, while the Sheepdogs worked during the day. They have a fascinating history - bred to look like a lion as a mascot for Leonberg, Germany, they were almost wiped out by World War II.
I guess we're the sheep now & Bruno works 24/7 as we have no Sheepdog for the day shift.
Of course, he takes a break whenever he needs one & now that he's in semi-retirement, his breaks cover approx. 20 hrs. a day, so I'd say he now works a 4/7 shift.... :-))
