Long message to non-reading cats snipped.

The best thing I ever taught the terrier was
the "BACK" command, which he interprets as
"walk backwards 2 or 3 steps and stop". Since
he is a terrier, every time I open up a hole
from moving boxes, machines etc, he has to
jump in the breach and check for rats. This
quickly became a pain in the ass as I would
often want to put the box back.
