I am reading all the different opinions on this.
I am a breeder and yes.... my girls are priced higher. Mainly because For every 10 people who call me.... 8 of them wants a female.....
There are people who only want males as well but majority are looking for little girls. And it's not a breeding thing to.....yorkies tend to be a breed women want. Girls want to tote them around and doll them up. It's completely subjective and it is JMHO.
But reasons can be different based on an individual breeder.
