23 Comments. 1  Red white and blue all the way. 51. 2  Bring back the Hawk! 6. 11. 3  Monochrome, but must admit that the overall effect (dollar grin inspired grill, positioning of tri shield) looks premium.

From about six months old to through the rest of her life, a female dog will experience estrus, or heat, roughly every six months.eat 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 youâll know the cycle is over when all her vulva returns to its normal size and thereâs no more bleeding or discharge.
Luckily, you can read more about how to calm a female dog during the heat here. Standing heat lasts for 7 to 9 days. After proestrus comes the second phase of the heat period â âestrusâ. Sometimes it is called a âstanding heatâ because it starts when your female is willing to breed and stands up when a male is trying to jump on her.
