Dog toy destruction

"We were just standing here and the skunk exploded."

My dogs prefer stuffed toys to plastic or rubber.  But most don't last very long.  

What I haven't figured out is the timing of the destruction.  Some toys are mere husks within minutes of being given to the dogs.  There are a couple toys that have lasted over a year, with no damage.  And some toys will be fine for a couple of weeks, then suddenly are destroyed within minutes.  

I am getting good at picking up stuffing.
