I'm thinking that the dog is Kate's....they are watching the Steelers game (Rebecca is wearing a jersey in the final scene)when the fire starts and Rebecca, Randall, Jack, and Kate get out.....Kate's dog is left inside, and she is distraught....Jack goes back in to get the dog and doesn't come out, but the dog was outside all the time.....hence, Kate blames herself for his death. Trying to figure Kevin and his leg out....did he play football? Maybe he broke it playing and couldn't stand to watch football so he went out with Sofie?

The character of Atticus Albridge was named after an 18 month old boy whose parents won the right to name a character at auction http://www.telegraph.co.uk/culture/culturenews/11177957/Downton-Abbey-Secret-of-Lady-Roses-hunk-is-revealed.html For that reason, I find it difficult to believe that he would be written as a cad in the end. More likely, the prostitue was sent to him as a trap because he is a Jew marrying a Lady (would Susan be that evil?). Also, he just seems too smitten with Rose to be a social climber. Maybe, just maybe, there will be a wedding on Downton that doesn't end in being left at the altar or early death....
