Breeding suggests it should be no issue. Doctor Dinos tend to get 2 and a half and being out of an Astarabad mare suggests age stood stay that’ll far. On breeding along she looks like a 2 and a half should be ideal.
I don't see this breeding angle - am I being thick?
Doctor Dino best progeny: State Man (2m), Sharjah (2m, maybe 2.5m now at age 10), Sceau Royal (2m), Master Dino (2.25m, but seems likely to have got 2.5m), Dinoblue (2m), La Bague Au Roi (3m, but dam sire Turgeon a proper stamina influence - Allaho, Asterion Forlonge, as well as Politologue and The New One), Fil Dor (2m), Gin On Lime (2.5m).
I look at the above and see a definite preference for 2m for Doctor Dino progeny in his best horses - doesn't mean they can't get 2.5m but they are definitely best at 2m
Astarabad best damsire horses: Lisnagar Oscar (3m, by Oscar), Dinoblue (2m, by DD), Blue Sari (2.5m, by Saddex), El Presente (3m, by Presenting), Kateira (2.5m, by Kayf Tara)
there are others, I just don't know the horses so have used the best horses I know
Looking at Astarabad, I'm unconvinced that he brings the stamina to his progeny as a damsire. Obviously it's a small sample, but I'm not convinced he brings more stamina to horses than Oscar, Presenting or Kayf Tara. It's probable he gave the stamina to Blue Sari given Saddex' other progeny (Editeur Du Gite and Haddex Des Obeaux 2 milers, Eklat De Rire 3 miler but by Video Rock, stamina influence from VR rather than Saddex I suspect) but on balance I remain unconvinced.
Add to this that Dinoblue has generally been a keen going sort it strikes me that 2m (for now) is best for her. Am I missing something or reading the pedigree wrong?
