Hey people - just because Sarah wants to change the sex of the dog to please her daughter doesn't necessarily mean that the daughter is a brat. If you're going to call anyone anything, direct your insults towards the enabler.

Sarah - if you continue to spoil your daughter in this manner, she will most certainly turn out to be a brat. I suggest that this may be the time to give her the 'you can't always get what you want' speech. If you love your daughter, you will teach her something about virtue, rather than indulge her desire to alter the sexual organs of her pet.
