Candy,
She is licking herself. This is why i thought she might be going into heat. My mom told me when they start to mature a little they sometimes do tend to lick/clean herself. I have not taken her to the vets for 2 reasons, Easter and a friend of mine has her sister and her sister has started to lick herself. She has not left any other signs of a heat cycle at all. No swelling and no discharge at all. She is a very active little pup and if I leave her for any length of time she will lick and not stop for anything. All I have been trying is to keep her busy! Anyways I am getting her in to get her chipped tomorrow and I will ask if this can be looked at as well. She was born November 11th so I guess she might be getting close to going into heat.
