Abraham loved people but he did tend to get a bit stroppy when he was around ewes, as he tended to be very possessive, she said.
Among the first to do so, the trio brought the breed to New Zealand about eight years ago and semen from their flock is now being marketed in the United States and Canada.
Mr and Mrs Strathdee met at Lincoln College 40 years ago but could never afford to go farming, Mr Strathdee becoming a financial adviser, and his wife a midwife.
Living on the edge of Christchurch's red zone, they were affected by the earthquakes and spent five years "fighting" to get payment for their house.
When it came through, it meant they were able to move to Motueka, buy 100ha and the intention was to run some cattle in their retirement.
But then Mrs Strathdee spied a photograph of the Valais Blacknose and was smitten.
The breed was "fascinating" and the very docile sheep tended to be more dog-like than sheep-like, she said.
Given the interest in the breed in New Zealand now, UK breeders were charging $NZ2000 to $NZ3000 an embryo.
