Tess,
I've probably over-posted on this topic, but dog attack reports, especially attacks on kids, are everywhere you look these days. It's something I am VERY opinionated on even though, in general, I try to see both sides of the story. Dog attacks are almost ALWAYS owner-related (through a lack of training, incorrect training, poor containment, lack of knowledge, abuse, bad breeding or all of these things combined) but the dogs catch the heat...either through euthanization or breed bans or just an undeserved bad rap. It makes me crazy when a dog attacks TWICE. I don't want that to happen with your friend's dog.
Here's a recent thread for you to look at. It involves dogs that attacked a child one day, and two days later attacked a few kids and a teacher in a school yard:

You'll see in the article that while the dogs were house-quarantined after the first attack, the owner's ROOMMATE let the dogs out while the owner was at work, and they attacked kids in the school yard. But is it the roommate's responsibility? No. It's the OWNER'S. The roommate may be a moron, but it is the owner's responsibility to make sure that dogs are not left in the care of a moron.
This is the kind of thing that can happen if the owners of dogs do not demonstrate the proper responsibility. And it also shows how unforgiving people are when it happens TWICE.
Now, I'm not saying I think Cookie is going to go on a wild rampage and attack every child that she comes in contact with. To be honest, she sounds like a nice dog that had an unfortunate, but canine, reaction. To be honest, if I were a dog, babies would scare the crap out of me, too. It's not like the dog walked by the baby and just decided to take a chomp out of the kid.
So I think I'm going to soften my stance a little. It's *possible* that this dog could live out the rest of her days with your friend's family, under the right circumstances and with the proper precautions. She's lived with the family for 4 years, right? With no other problems...no growling, anything at all? And she's a rescue dog, right? For all you know it's possible that she lived her first 2 years with a family that allowed a baby to chew on her tail as a teething toy. We'll never know and it doesn't really matter. Strange kids are not an option. Kids outside of the family are not an option. No second chances, remember?
However, if the owner of the dog 100% trusts that dog around her own children, then pehaps she can stay in the family. She'd need to be crated when anyone outside of her "safety zone" (anyone else, in other words) comes over. If needs to be taken around other people for any reason, she needs to wear a quality muzzle. No exceptions to this, because again, NO SECOND CHANCES.
This is of course, only an option that is suggested from someone you don't know, online, about a dog I have never met concerning a situation I didn't see.
Ultimately, your friend will have to dig deep and see if she can trust, TOTALLY trust, her dog around her kids. Because there are going to be plenty of unexpected situations left in the dog's life.
For example, my 8 year old son, VERY calm and well-schooled in proper dog-human interaction, accidentally tripped and landed on my GSD's tail with his full weight. Now in my situation, my dog yelped and then scrambled up to lick him to death. What do you think would have happened if it had been Cookie who got stomped? No matter how careful you are, there will always be situations that will boil down to the dog's individual temperament.
If she CAN'T trust the dog 100% with her kids, then she should rehome the dog to people who don't have kids and are very responsible and alert and aware of the situation. It will be hard for everyone--your friend, her kids, and the dog. But the right thing isn't always (or even usually) the easy thing.
But, please, don't let her consider euthanizing the dog. He's not a bad dog, from what you've described, but maybe just a dog that's an improper fit for her family.
Please keep us posted. I'm sure we'd all like to hear the results of the temperament testing and what your friend decided to do.
If she does decide to keep the dog, try to talk her into joining this board. People can be very blunt, but they are honest and IMO, this board has a bigger wealth of information than you will find almost anywhere.
You sound like you're intelligent and open-minded and best of all---you're seeking help. Your friends sounds like she wants to do the right thing, and she's got good support in you. All good signs.
Your friend has a really hard decision to make, and I don't envy her position. I wish you all the best.
