And children can be temperamental around bitches LOL
Fact is, it's a personal matter, as the two posts above show. Me, I'd go for a bitch , on balance. I'd take generalisations about dogs with children with a pinch of salt.
There's often a bigger difference between the temperaments of two dogs or two bitches of the same breed than between the two sexes generally; one dog, or one bitch, may tolerate children better than another and be different in other ways, too.
The difference in temperament and character between breeds accounts for more than the sex does.That's the place to start.You need to know what the breed is like first.
That said, and generalising, bitches tend to be more sloppy, more openly affectionate, than dogs. Dogs of the same breed tend to be a bit more distant. Dogs are more inclined to wander whereas bitches are home bodies , except when they're in season.Then you can lose one for quite a while,if you are not careful. Then they are out following their instincts: they may bring home more embryonic dogs than they you had before! Dogs don't do that: they leave the products with some other owner ! The other side of that coin is that a dog that gets the scent of a bitch is a pain to have around. All dogs urine - mark territory far more than bitches.That can be a problem: he'll mark anywhere he gets the scent of any dog,including when visiting.He's more likely than a bitch to stop at every lamp post and anywhere else where another dog has been (and then mark the spot, too)
Dogs have a stronger smell than bitches (which may not matter if you bathe them a lot)
They are more likely than bitches to get themselves into fights.
That's about it.
