As a matter of reference for all involved here is how we are going to tell them apart:
Austin hates baths - Ehren loves them.
Austin barks at people she doesn't know - Ehren smiles.
Austin is cool to sleep for 8 to 10 hours - Ehren is NOT.
Austin hates traveling - Ehren seems to be fitting into the Fykes world traveling quite well.
And the most obvious... Austin has white hair - Ehren has black.
Should be simple.
