Boston terrier eatting dog poo!

Question
Hey, I hope you can help me. Of the three dogs I have my youngest a 9 month old boston terrier "Hannah" has developed a discusting habit...she is eatting dog poo from outside, I know this because she brings frozen poo in from outside whee I have caught her three times not yelled at her she dropped it and I get a tissue and fling it back out. Right now all the dog poo is frozen on the ground and I can not remove it at this time..I must wait for the weather to milden so I can get it up. All my dogs are eatting authority from petsmart its high quaility and has no byproducts so there not a crappy diet.   My questions are:

Why has she started? this I've had her since she was 7 1/2 weeks old and she hasnt done this before

How can I stop the behavier as soon as possible?

thank you for any information you can give me.

Answer
Hi Tara,
Your girl Hannah may be doing this for a few reasons, one is low iron. Even the best foods don't cover the extra need some females have. As she matures her body requires more especialy during heat cycles if she is not spayed. Another reason is she is showing her subservience to the other dogs. Yet another reason is she just likes it. You can get from your vet, you don't even have to take her in, just call them and you can pick it up, not expensive, a powder to put on the food that will stop her from doing this. This is really the only way I know to stop it.
Luck to you...Lisa
