I can state unequivocally, that race horses are pampered much more than household pets.
I know the horseracing world inside out from trainers to stable staff, jockeys, owners pundits, vets and behind the scenes staff.
No racehorse will run if it doesn't want to.
You simply cannot make a horse run.
The whip is a very small strip of leather on a stick, can only be used as a tap a very few times to 'encourage' (number of taps differ between countries) and only on a particular part of the horse, not randomly.
Yes, UK whip rules are being revised but importantly, horses actually look forward to racing, are checked by vets immediately after racing and they particularly look for marks on the animals hide.
There should be none, as a light tap would not mark.
Horses are treasured and pampered, they are costly to keep but can earn their keep many times over. Some are worth millions so neglect and cruelty are definitely no part of legal horseracing.
Yes, some unfortunately have to be put down through illness or injury but so are household pets.
Humans have bred cats and especially dogs to be beholden to an owner, live indoors and eat manufactured food.
Cat, dog and bird owners buy them for their own pleasure, not because the pets choose to live with humans.
They were all feral in the first place.
Racehorses are bred to be ridden and although flat jockeys are lighter and can ride younger animals, jump jockeys are routinely much heavier and the horses older, as are those bred for show-jumping or other kinds of races abroad.
I wonder how many pet lovers would ban Crufts. ?
I think it's much more important to address meat, fish and fowl and the methods by which it arrives on your plate.
Proper race horses are loved and cared for, during and after their glory days are over, many going on to have other 'careers' in other equine fields.
They may be gone from the track but never forgotten by those who 'knew' and cared for them...as are many household pets.
