All had different owners. I'm definately one to think that the majority of a dog's behavior is directly related to the upbringing. The females just seemed a bit off to me. Two of them (one I worked with here in Santa Cruz, the other in LA) were prone to fear biting, the other was just very timid, shy. Both of those females (weird as it may seem) had male wheaton terriers in the family that were pure joys! Those females ranged from 1-5 years old.
The two altered males Bouvs I've worked with were absolutely WONDERFUL to be around. Just super goofy, sweet and playful. I thought the males were better looking as well.
I was doing a little reasearch...
"This breed needs an experienced owner to prevent dominance problems. He should be socialized well at an early age to avoid over-protectiveness and shyness".
It could very well be that the females just didn't have enough of this as pups...who knows
