* Varying numbers across locations: The number of greyhounds bred for racing varies significantly depending on the country and region.
* No centralized global database: There isn't a single, comprehensive database tracking all greyhound breeding worldwide.
* Changing trends: The popularity of greyhound racing fluctuates, which affects breeding numbers.
However, we can give you some context:
* Estimated global number: It's estimated that tens of thousands of greyhounds are bred for racing each year globally.
* High numbers in key areas: Countries with strong greyhound racing industries, such as Australia and the US, likely breed the highest numbers.
It's important to note that the ethics of greyhound racing are often debated. Concerns include animal welfare issues, such as injury rates and the fate of retired greyhounds.
