re: Dog just snapped at daughter

Anybody who wants to learn to raise dogs should read water dog and walk with wick.

Good dogs are great, but there's no room on my earth for bad dogs. All that bullshite about "raise them right" and "no dogs are born bad" etc is just that, bullshite. There's no point in risking it. Sure, you can correct bad behavior. It's still an animal. If you're going to have a dog that mingles with children, you had better be 100,000% sure that there isn't a shred of aggression in them.

An aggressive dog can be ok in certain circumstances. A cow dog for example is not going to be hanging out with your kids at a BBQ. It's either in its pen or biting cows. It is in no capacity ever in its life a pet.

A working dog that serves double duty as a pet has to be the best of the best, and they will all test you to see who's in charge. OP did the right thing. The dog is a pack animal, and somebody has to be the alpha. Make damn sure he knows he's at the bottom of the pecking order.

Male labs can be such block headed assholes when they're young. They all have that moment when they push you too far and hopefully it only happens once.
