Aha!  The electric fence / urination thing!  Eyewitness acount here: we used to use flexinet electric fencing on my smallholding about 20-25 years ago.  Friend's visiting dog trotted out one morning, cocked leg up to said flexinet, screamed, and shot back into the house with tail firmly tucked between legs.  And then proceeded to engage in a really thorough 'make it better' washing of genitals.  And flatly refused to go anywhere near the area where the evil monster had bitten his 'bits' for quite some time! Sooooooooo - if you could actually have asked him what the effect was, he may have been able to provide some first-hand evidence, lol!
