"Where are you taking your dog?"

Translation: Ble dych chi'n mynd â'ch ci?

[AlanNason]

With the second solution-surely 'Ble wyt ti'n..' doesn't agree with 'a'ch..?'

[rmcode]

Yes, the second part of the sentence should agree with the first part and it should have read:-

Ble wyt ti'n mynd â dy gi?

However since this lesson is about comparison and this sentence is nothing to do with comparison it's now been replaced with a more suitable one.

Thanks for the comment and for bringing this to our attention.
