Tassle (BCx) was 11 months
Trip (Gundog x) was 14 months
Siren (BC) was 11 months

My friends Mini Poodle was 14 months.

Chaos (NI) was around 18 months and on adult food

this is interesting. lily, jack russell, is nearly 7 months and no sign yet of her first season.

reading this thread makes me think that i may have some time yet before anything happens!

Me too! Werm is exact same age and no signs!
Is there anything I should be thinking of for when she does (other than not let her out of my sight?!)
I just realized that all other bitches I have had have already been spayed as rescues so have never had a season with a bitch!!
Ohh this must be how my mother felt about me!!!!
Feel like I should do her a 'first season' or 'womanhood' party!!!

Gypsy has just started her first season , she's 14 months old

6 months for all of my girls

my Lhasa Daxie cross was 6 months, my NI was 10 months.

Both of my Dobermann girls were around 10 months for their first season.
Rio was on Junior food and Milan had been on any old cr@p she could scrounge for most of her puppyhood.

Zena was 9 1/2 months, but her sisters were one week earlier, each one, if that helps? She was on puppy food until one year old too, never adult food up to then.
