What would be the result if mated with an Aussie yellow?

That is like asking what happens if you cross an Aussie terrier with a Chinese Hairless dog. You get mutts.
As I have seen the results of such a crossing - many years ago in the didn't understand that they were different days - They would be visually a mix of both. But not pure strains of either, and could not be sold as anything but mutts.

For a start don't do it. DF Euro yellow is sexlinked dominant and Australian yellow is autosomal recessive. All young will be EY in single factor and all will be split for Australian yellow. Any normal looking young will be split for AY but not EY as you can't get split EY's
