With the greatest of respect Lout racing can not survive without the use of Therapeutic substances... they are what they are and have a genuine Therapeutic use, if Trainers did not use them in the care of a horse they may well have an animal welfare issue..
That is partly the reason drugs like Altrenogest and ulcer treatments were recently removed from the prohibited substances list so that trainers could use them without fear of a penalty we were however about 10 years after the gallops who saw the problem much earlier and changed their rules.
