The kennel facilities were at nearby Cefn Mably in St Mellons and the leading event was the Glamorgan Cup held over 500 yards.

[4][5] In 1937 the Greyhound Racing Association closed the nearby White City stadium, leaving the Arms Park as the sole Cardiff venue.

The Welsh Derby was won by the likes of Trev's Perfection (who completed the Triple Crown in 1947), Local Interprize, Ballycurreen Garrett, Ballylanigan Tanist, Endless Gossip, Rushton Mac and Mile Bush Pride in a golden era.

The event was so popular that despite the stadium being taken over for the 1958 British Empire and Commonwealth Games the track was re-laid in time for the Welsh Derby to take place in October.

The north ground was subsequently demolished and a new rugby union stadium built in its place for Cardiff RFC, who would move out of the Arms Park because Cardiff Athletic Club had transferred the freehold of the Arms Park (south ground) to the Welsh Rugby Union in July 1968.

The last meeting was held on 30 July 1977 which attracted just 1,128 greyhound fans who witnessed Lillyput Queen, owned by Cardiff butcher Malcolm Davies and trained by Freddie Goodman, win the last race.
