I have a girl I decided to place and had planned to spay her next week.
Today there were spots of blood in her crate.
At what point can you spay a bitch when you see color? Now? In a month?
I want to do what is best for her of course.
I asked two vets and got two different answers!

two months after her cycle is over, which is about 3 months after you see color.

Is this her first heat?Let her go through her first heat so that the estrogen enables her growth plates to close.Definitely wait another three months.

If the new owners want the dog soon, go ahead & spay. Believe it or not, vets spay more bitches in heat (cats too!)than not. She'll be fine.

"Is this her first heat?Let her go through her first heat so that the estrogen enables her growth plates to close.Definitely wait another three months. "

That is how I would do it even if she is older. Excellent advice given.

Thanks for the replies.
I forgot to mention that my girl is 16 mos old and this is her second heat.
I will wait the three months as what is best for her is the most important.
