When are horses coming on minecraft PE?

My sister said horses will come on minecraft PE on ipod on the new up date 0.9.0. But instead of horses it was wolves please tell me what update example 0.9.0 and tell me when the up date is coming example Thursday 10th July.

1.6 but thats a long time ago. 1.8 is already coming

New latest update was awesome but your right where are the horses, might come in the next update probably
