My preferences:
-Loyal to a family not a one-man dog
-friendly/social with people and other dogs
-quiet..most of the time. I don't mind a warning bark that someone is at the door but I can't stand a dog that barks for 10 mins after someone comes in the door!
-active but not maybe not hyper
-smart dog that is easier to train
-protective would be nice...but not needed.
-short hair preferred or low shed.

Any suggestions?
Update: I want a low shed dog because I am allergic to the hair/dander..? Also the protective instinct isn't a must.
