The long story short, regarding an incident in the afternoon of February 27th EST, is this:
Reilly and Camille made another good call in barking when they saw a notorious fence-jumping neighborhood pitbull from the window by the computer, though they really shouldn't have been barking—besides, as "Momma"/"Auntie Nicole" told Reilly, Reilly and Camille didn't need to worry about the other puppy.
Also, "Momma" thankfully had Reilly's harness and leash on Reilly when Fence Jumper* came and ran along the side of the fence that is opposite to the back porch. Then again, Fence Jumper could've jumped into the yard and continued to disobey her owner instead of eventually going back to her family's house**. Either way, Reilly and Camille—notwithstanding that their barking alerted "Momma"/"Auntie Nicole" to Fence Jumper's escape and run in the neighborhood—ended up not having to worry about her.
* Real name withheld. Also, Fence Jumper is a sweet pitbull and one whom can be aggressive in spite of her sweetness.
** That may've created a situation in which "Momma" would've needed someone to help her and Reilly.
