When Do Greyhounds Go into Heat?

Generally speaking, most Greyhounds' first estrus cycle

occurs later in life than non-Greyhound dogs, occurring near or after 12 months of age. The female Greyhounds' estrus cycles are also not as frequent as non-Greyhound dogs, occurring every 9 months vs. 6 months.

What age do greyhounds come into season?

A heat/season is the fertile period of a dog's cycle when they can get pregnant. Dogs usually have their first heat at around 6 months old, and then every 6-7 months afterwards. Each heat tends to last approximately 16-18 days.

How long does a Greyhound stay in heat?

Heat usually lasts between 2-4 weeks. Early in the cycle, a female dog may not be receptive to male dogs, although some are receptive through the entire cycle. It can be shorter or longer and you'll know the cycle is over when all her vulva returns to its normal size and there's no more bleeding or discharge.
