Hang on... the horse is hurting so you merely deaden the pain (not correct what's causing it, quite possibly aided by the impact of NH work) and carry on? That doesn't quite fit with giving away horses which presumably aren't career-worthy any more. And so what that you give away over 20 horses a year to 'good homes'? Does that mean that HJ chews up 20 horses every year which are no longer fit for purpose, Mr Wylie? Because that's one helluva big turnover in discards from one owner/trainer, that's for sure.
And, yeah, I'd kinda hope serious medications would've been administered on veterinary advice - I would hate to think what things would be like if your trainer could freely DIY anything more than Neat's Foot Oil, to be honest. And it's part of his job, not yours, to explain why the anabolics were administered, and why he kept racing horses on them in an affront to the rules of racing.
Jeez, look: the hole is already Newcastle pit size. Why dig it to Great Hole of Kimberley proportions?
