What would you do if your dog bit someone?

First up I want to clarify that there are some situations in which people deserve to be bitten. Like, if someone attacked me I wouldn’t mind Dakota attacking my attacker with everything she had. If someone kicks and beats their dog, they deserve to be bitten.

But consider my question in the following context:

My daughter is in the unfortunate position of have to temporarily stay with her fiance at his mother’s and aunt’s house until they can find some place else. They have this yappy little dog. The dog barks constantly and is constantly waking the twins up from their naps.
When Brande and Aden visit they can’t crawl around on the floor chasing the twins because the dog comes unglued, growling and snapping and acting like he’s going to attack.

Until today, though, he’s never actually bitten any one.

Savannah, 14 months old, was toddling around with a book in her hands and she tripped and fell on the dog’s hind end. The dog spun around and bit her on the face.
Savanna started crying and the mother, Ruby, picked her up and said, “Oh, poor baby. Did Precious scare you?” Savannah had blood running down her face and a pretty deep puncture wound on her cheek.
Corrie came unglued. It was just the last straw of many, many straws with this dog. She screamed “HE DIDN’T SCARE HER! HE BIT HER!!!”
Ruby said, to the dog, “Now Precious. You should be ashamed of your self.” That’s all she did.

If my dog tended to snap and growl at people, that dog would be re-homed immediately. If my dog ever actually bit someone under circumstances like that, that dog would be re-homed to heaven.
