Hey,
maybe she only had a "quite heat" (you know, when she is not bleeding) and you didn't recognize it? My PJRT bitch had the same.
And I had another one that didn't come into season until she was 1.5 year old.
But anyway: she yet needs to proove herself in work, so you have 1 more year (at least) until you will want to cover her. Don't you?
ATB,
Anna
yes i want to cover her around 2-2 1/2 yrs old i'll just have to keep an eye on her now
