I rescued a puppy and I am wanting to know if it is a Shih Tzu. I have had people tell me it is and also people tell me that they think it might be a Lhasa Apso. I have an appointment this month to get her in to get her the shots and spayed. I don't care either way, she will have a loving home for the rest of her life. I am just curious. I am also curious as to what age she looks like. She weighs around 5 lbs.
