When Do Dogs Sexually Mature?

[karleee]

for my last dog,i never actually really noticed when she sexually matured,but with dazzle (she is turning 7 months tomorrow!) I was just wondering when they start actually coming into heat?

My eldest sister (21) is staying overnight and her 6 month old pedigree show bordercollie (obedience,agility) and he kind of wants to hump everything at this stage....including dazzle

She hasn't come into heat yet,but i was just curious what the average age is?

thankyou guys

It's different for each dog. They can come into heat from 6 months on.
Jinx came into heat, last june, for the first time at 14 months.
