St. Bernard mouthing me

Question
Hi, I have a female St. Bernard who is 14 months old.  When she gets excited she opens her mouth and put it around my ankle, arm or hand.  She does it others in the family as well. She doesn't keep her mouth there just a quick little mouthing.  What is causing her to do this.  We got her when she was a year old so I am not sure where this comes from.
thank you for your help.

Raeshelel;
This is to show who is the "Boss"!
Obviously, she is in need of some training, as you do not want to have her take a chunk out of someone's arm!!!
So, I would get yourself to a class as soon as possible.
When you can, check out the "Petsmart" to your area, as well as your Vet for some options to find an obedience class.
This will be most important.
When you "Rescue" a dog, you never have any idea who the dog has learned what from.
So, it is super important to start the training NOW!
Let me know how you do.
