Finally I redeemed this task at the electric fence. SubDog was put in metal chains ⛓️ and collared with a heavy metal collar.
The leg chains made sure I had good contact to the ground to intensify the ⚡️!
Thanks to @jimsmith1993 , who pointed out the obvious! 🙏🏻
Unfortunately the pissing was still not working. But directly having your glans pushed on the electric wire, is really a painful buzz.
