So I have a black Labrador dog.... she's 12 years old and just stopped breathing earlier...... I don't know what to do! 

Could my dog be leaving? Is she gone? Is she dead.... I don't want it to be true... I loved her so much but it is the end of her life...,

So..... I guess my dog has the possibility of dying today.... I'm so sad....

And that's her.... her name is Liz.....
