* Lifespan: Greyhounds typically live 10-13 years.
* Breeding Cycles: Female greyhounds come into heat (estrus) every six months.
* Pregnancy and Litter Size: A greyhound pregnancy lasts around 63 days, and they can have litters of 4-10 puppies.
* Ethical Breeding: Responsible breeders do not overbreed their dogs. They will often retire a female greyhound from breeding before she reaches a certain age or has had a certain number of litters.
It's important to remember that breeding dogs should be done ethically and responsibly. This includes factors like:
* Health: Both parents should be tested for genetic conditions common in greyhounds.
* Temperament: The dogs should be well-adjusted and have a good temperament.
* Placement: Puppies need to be placed in loving homes that are prepared for a high-energy dog.
Instead of focusing on a specific number, it's more important to understand the ethical considerations of breeding and the needs of greyhounds.
