Sorry Sen your post on greyhound racing is full of fallacies perpetuated by people with no knowledge of greyhound regulation.
As the only licence holder here I can assure you that abuse is extremely rare. Doges are in track kennels once per week at most for up to three hours.....the track kennels are well heated and lit.
As far as regulation goes greyhounds are the best protected and regulated of all animals. When my dogs finish racing I have to either keep them as pets, pay to have them rehomed with a registered homing agency, or re-home them myself.
If I choose the latter option, I have to provide the name and address of the new owner to the Greyhound Racing Board of Great Britain, the board then sends out inspectors to examine the new home to make sure it is suitable and follow up with other visits to ensure that the dog is being well looked after.
It is in the interests of all trainer to make sure the dogs are in good condition....the typical feeding regime of these dogs is much superior to that of many humans, as are their living conditions which are inspected regularly.

I wish people like you would take the time to visit a racing kennel(they have regular open days) before knocking a great and historic sport.
