I had to laughl, but when I left my trailer in the back yard, with a load of bluestone crusher dust over lunchtime, our pup attacked it.
I cover the load with an old trampoline mat tied down with rope. The pup chew through the rope and dug out a lot of the dust, spreading it for a few metres around the trailer.
She also ate about a 20 cm length of the trailer's wiring.
