To me, all the Eeveelutions look very similar to a fox; just because they have a different type of mouth, doesn't exclude the rest of their body.
They've obviously been altered a bit--if they hadn't, people would complain about their design. These Pokemon look a lot like the fox picture you posted, especially Flareon.
I need a new sig, uhg.
