No wonder then they were in the back yard - no one to raise any kind of alarm. If Shelley is territorial then Ruby will get there :) Blue will lick someone to death or jump up on them. Belle is more standoffish, could be she’s taking her training from the queenslands beside her. Her personality is completely different from Blue’s, as is her behavior.
I've found the Lab boys to generally be a little goofier and friendlier than the girls. Although you'd be hard put to find two more friendly Labs than mine! I was afraid they wouldn't pass Canine Good Citizen on Monday, because they love to hug and kiss EVERYBODY - but they were on their best behavior, thank goodness, and both passed. (I wasn't really worried about Shelley, she's a well trained dog, but Ruby the Egregious has a very thin crust of manners over a volcano full of Crazy Puppy . . . )
