The result of crossing a pig with a doe? (3-3)

I believe the answer is:

pie-dog

I'm a little stuck... Click here to teach me more about this clue!

'the result of crossing a' is the definition.
I can't judge whether this definition defines the answer.

'pig with a doe?' is the wordplay.
'with' is an insertion indicator.
'a doe?' becomes 'edo' (I can't explain this - if you can you should give a lot more credence to this answer).
'pig' placed around 'edo' is 'PIE-DOG'.

Can you help me to learn more?
