> COI of 22.75% seems rather excessive.
I think, but don't know obviously, that as HM was involved in breeding her livestock (racehorses, Fell ponies cattle and so on) it was, for her, more about breeding for the positives in their 'working' lives than anything else. Yes, they all had to be 'fit for purpose' which would include conformation, but I see her breeding as more to do with 'fit for purpose', than anything to do with COI. Livestock breeders know when they need an outcross to prevent their stock losing vigour, size and so on but would mainly breed for what they needed within their working lives. Having lived on a cattle (breeding mainly) farm out in Canada for some years, I saw first hand what he needed within his stock. It was interesting.
I can't help worrying about those Corgis and mixes and hope they will be collected by Andrew/the daughters, asap so they can settle into their new lives.
