I have a 8 mo old male Great Pyr. He is just a big teddy bear. Loves
to get hugs (OF course he has to for some reason nibble on your ear)
He has done that since I can remember. Sorry lost focus for a
sec...Ok, To the point...He has this issue with chewing sometimes. It
could be anything but it is usually something like a shoe. My gfriend
has found many of her shoes destroyed. Weird thing it is not all the
time but it is often enough to be anoying. (Hey that will teach her to
put the shoes on the steps to go upstairs)

Is he bored or is it something else? Any ideas about how to curb this
behavior? Any advice would help.
