Does a 115+ pound dog need a pacifier? Look carefully and you will see her pacifier, the white object, sticking out of the side of her mouth.
Here is a little better view. She doesn't chew them up, she rolls them around in her mouth, throws them in the air and falls asleep with them sticking out of her face.
Or sometimes she just wanders around looking like this.
Here it is, sans dog. They can be found in packs of two at your local Big Lots store. You have to look really hard to see any teeth marks. There are a few on the left side of the doorstop near the top.
