Wow, thats really bad news, but arent you glad you know that rabies is something you and your family need to be concerned about?
It really is too bad your poor loyal friend had to be sacraficed for this knowledge, but better than one of your kids.
Skunks are just all bad news, like I said they are the #1 animal in the country to be worried about rabies.
I was told by my friend that at least 80% of skunks carry rabies, and the other 20% will get it eventually.
Just because a skunk doesnt show signs, you should ALWAYS treat it as if it does.
Granted, in some parts of the country its more of a problem than in others, but no matter where you are in the US if you see a skunk you should immediatly think "RABIES" and not "stinky stupid skunk".
I really am sorry about your dog, that really hits home for me as my jack russell terrier constantly hunts for animals in holes, and ya never really know whats down there till he comes out, and my first thought everytime he goes down is "$h!t, Rabies".
I totally believe you are doing the right thing by taking her in tho, she will cause problems and it wont be her fault.
Im really bummed about this.
Edit-
I dont believe you can contract rabies merely by coming into contact with infected saliva, the infected saliva needs to contact a deep open cut or scratch or a mucous membrane such as your nose or eye.
I have trapped many many skunks, I wear heavy leather gloves and wash my hands with bleach cleanser when Im done.
