drsaari, nice lookin' little chocolate there!
I have a full bred female, about 6 years old now, and she is a hell of a watch dog...fiercely protective of stuff that is considered "her turf!"
However, once she is introduced to someone, she always remembers them and is very cool with them! (We had hardwood floors put in a year or so ago and a couple guys on the crew were a bit "iffy", if you know what I mean. Turns out that when the crew came back a couple weeks later to finish out some trim work, she was cool with the guys that were OK, but the iffy guys, she still looked at them with a cocked eye!
Nemo me impune lacesset! (No one will provoke me with impunity!)
