Borador

Question
I have, what I believe, is a Borador. That is; a Labrador Retriever + Border Collie mix. It's considered a designer breed is what I've been reading. I did get blood work done today as part of her bi-annual physical. However, on the adoption papers it says that she is an Australian Shepherd, full blooded. While the actual adoption agency representative said that she looked to be a Spaniel/Collie/etc; mix.

This is a picture of her. Her name is Holly.

This is a picture of only one combination of Borador:

In my opinion, she looks too much like a Border Collie + Lab Mix than an Australian Shepherd.

It wouldn't matter to me either way, since she's a smart, loving, sweet, quick-learning dog with 50 lbs of boundless personality. I was just wanting someone else's opinion.


Also a more specific question; the bloodwork that she had done today, would that be able to determine her breed(s) or would that have to be something special I do later?

She is a year and a month. She has been spayed. It's a female. She weighs 54.4 pounds as of today.

Answer
Every Lab cross I have ever seen including Goldens, Irish Setter, Flat Coated Retriever, and maybe a BC had short hair.  Don't Aussies have erect ears?  I would go with the Spaniel/Collie/etc; mix.

I think DNA testing is limited to yes/no on a certain dog being a parent, it can't determine the breed.
