Training racehorse

Question
I note past questions on Bute (butazolidine) and Lasix (frusemide)- to reduce the likelihood of lung haemorrhages. I note you don't appear to do this yourself. The potassium loss alone which accompanies the excretion of frusemide via the kidneys can give rise to abbherrent and even lethal cardiac arrythmias. Arrhthmias can interfer with blood pressures.

Are these lung haemorrhages more frequent in young horses (2yo)?
Have you see Rune Haugen's training methods?http://horsehrm.com/index.php?option=com_content&view=article&id=71%3Arune-rules-in-norway&catid=43%3Aarticles&Itemid=200024&lang=de

He appears to be a thinking trainer with reduced equine breakdowns.

Answer
I am not a veterinarian, but based on my own experience, I don't believe that bleeding is any more prevalent in young horses than in older ones.  I am unfamiliar with Rune Haugen,  but I will certainly check out his site when I have time.
