We CANNOT keep her. Our cats are very afraid of her-to the point to where they've peed on everything in the house and refuse to eat at times. I hate to say it, but when it comes between a dog I found on the streets and my cats that I keep as pets.....One has got to go.
Thanks to those of you who offered support and I apologize that it didn't work out the way we all wanted it to.
