What is happening today?! Today is so shitty.. I go to take our Dane out to pee & he takes off with the leash wrapped around my knuckles.. he almost ripped my arm out of socket & my pinkie got stuck in the loop.. My finger is huge & I'm sitting at the Urgent Care.. I know it's broken.. I can't even move it.. & they obviously can't do a X-ray because of baby.. so what do they do?
