The 99 greyhounds of which the guess was that many, but not all, were killed for being too slow? Yes. So? That proves that every mass grave is greyhounds I guess... Who'd also have thought that a trial track that has a base residence of x(?) number of greyhounds and hundreds of dogs going through it every week would have a grave with 99 greyhound carcases. As I stated before, my old home in suburban Melbourne has the graves of 5 dogs there, which is every dog we'd owned by the time we left.I know a mass grave of greyhounds has been found - is this not the case?
