Rose softly kisses the Doctor's cheek. "I'm sorry, I know if it were up to you, you'd let him go." She apologized knowing just how the Doctor felt about it. She then stood up straight aiming the gun at the dog shooting at it, hitting one of the muscles in the legs to make it stop moving. Caitlyn sighs stopping from running dusting her pants off. 
"I have a feeling you spared its life." Caitlyn said turning in the direction of the TARDIS as she spoke thinking she was talking to Rose, who turned her around.
"I did. I just shot at it's leg. But if it wants to continue living, it should get out of here and away from us. There's no way I'll forgive it, if there's real harm done to the Doctor." Rose said seriously and went to the Doctor and Jack seeing what she could do for the Doctor. Caitlyn stayed where she was controlling her breathing and once more centering her thoughts on something calming.
