A piezoelectric dog trainer is a small enclosed shell containing a piezoelectric element with a push button attached to a slidable loop. The opposite end of the loop extending outside of the shell is attached to a dog's collar where two electrodes leading from the piezoelectric element are attached. On the back end of the trainer there is attached a leash. When the dog pulls on the leash or the leash is tightened, a shock is generated on the dog's neck.
