So what about the beginning?
(1st Doctor: )
(2nd Doctor: )
(3rd Doctor: )
(4th Doctor: )
(5th Doctor: )
(6th Doctor: )
(7th Doctor: )
(8th Doctor: )
(War Doctor: )
Okay well, let's see here.....
1st, most definitely an owl. Because Doctor Who who! that's why. although not particularly a wise owl, if I remember correctly from those episodes.
2nd, I'm not sure. perhaps a raven?
3rd, maybe some sort of large cat? Lion perhaps?
4th, Cocker Spaniel!
5th, arctic fox
6th, hyena.
7th, Toad maybe?
8th, snake... indeedy-do
John Hurt has to be a dragon. Although I may be a little bias here considering he played the dragon in Merlin. I can't see past it!

Well, I'm off to bed, what do you guys think?
