Rose (Rise of the Cybermen)
From Tardis Wiki, the free Doctor Who reference
Rose was the Yorkshire Terrier that belonged to Jackie Tyler in Pete's World. She seemed to be that world's alternative to the girl Rose in the Doctor's universe, who was Jackie and Pete's daughter. This amused the Doctor, who quickly stopped his giggling to avoid upsetting Rose. She was at Jackie's birthday party when the Cybermen attacked. Her fate during and after the attack is unknown.
