"Doctor!" Rose shouted scared as a rock hit the dog on the head Caitlyn glaring. 
"OI! Mutt face, get off him!" Caitlyn yelled trying to distract it. She knew it wasn't friendly, but hell, she wasn't about to have her cousin going through the absence of the Doctor in her life again. She had to get the dog to come after her for a bit so that at least someone could shoot it with the gun that Jack had brought. "Who wants just bones to eat eh? Well, come at me!" She yelled and took off once it took her words seriously. "GET THE GUN AND SHOOT IT PLEASE!" She said having no idea where she was going, or really where the dog was, just using her instincts to slide to a sudden direction and immediately getting up once more running in a random direction, Rose tending to the bite mark taking the gun looking to Jack. 
"Here, you give him treatment, I'll hit the dog thing." She said standing up. She shot a gun before, sending the mind of the Devil to the Black Hole, but never before to a moving target and where she could possibly hurt her cousin.
