#4 Dog racing still takes place in Australia, the USA and particularly in Ireland.
Greyhounds are primarily bred for speed in order to make big money at the races. Old dogs that can no longer perform well are simply "disposed of". In fact, killing greyhounds that have become unusable for the betting industry is legal in Ireland.
#5 In order to put an end to this practice, racing greyhound rescue associations have been founded in many countries, which take care of the placement of retired dogs in families.
In some countries, such as Germany, greyhound racing is only carried out as a hobby for dogs, owners, and greyhound friends. Wagering is prohibited here. Thanks to these efforts, many former racing dogs have found new homes. In the US and other countries (except Ireland) there are now more racing dogs in families than on the track.
