I've seen this raised a few times, and I've been thinking about it a lot. It's more just a post of my thoughts a queries, not a preach or a lecture because I don't enough about it but I thought it might be an interesting discussion. Firstly, i was thinking about horses. A lot of breeding for horses is for performance horses. I know dogs probably differ but thats where my thoughts begun, breeding performance horses. I totally undersand wanting to keep the lines in breeds that reflect their original purpose (ie: herding BC's) but do wonder if therecould be a third ethical breeding pathway (the other 2 being conformation and work/original purpose) As performance sports gain popularity in society, would it make more sense to have specific performace lines. Dog's with speed, agility, willingness to learn, wanting to work in close with their handler, with an off switch, etc. In other word "instincts" that would help. I woudl say no, this is not a good idea, except then it comes back to conformation comps. Those dogs are bred forlooks, as opposed to working ability. Many working breeds in the show ring don't reflect what a good worker would be imagined to look like and may have little to no working instinct left. Like I said, not an argument. Thought it could be an interesting discussion.
