Heat question - Page 1

I have an 13 month old female who has not come into heat yet (unless it was a silent heat).

I did not have any males to warn me about it until 1 month ago that I got my first male.

Having asked the vet he said that he has seen females coming into heat even when 22 months old. Is this normal?

Is there a way to find out if her reproductive system is OK?

Thank you all in advance.

Actually it varies just like in people only reason I know this is because I used to breed chocolate labs many years ago and each female went in heat at a different time in their lifespan even had one at 25 months finally go in it.

You can get her tested fertile test but its expensive.

One of my WGR show line females didn't come into a full blown heat until almost 13 1/2 mos old. But I've heard of other show females coming in around 6 1/2mos old.  So it pretty much depends from individual to individual.
If a female is very meticulous and clean, they can keep themselves pretty clean so that you might just miss it, especially if there's not a male around to let you know. If you keep a female around other females in close proximity, they usually will trigger each other to come in heat.
You should be able to take a look at her privates and tell if she's been in heat yet. Females who haven't been in heat have very small private areas-still puppified. Once they go thru heat, they usually swell and then stay larger.
Other than that, watching close and waiting is the only thing I know you can do.

my gsd girl spunky just had her first heat at 14 months.
