Well my boy Boo has been observed on a couple occasions trying to push paddock mates through electric fences so he can get through with out getting the shock.
He is a terrible little devil for testing fences to the limits, especially electric tape.
He was spotted by my cousin trying to coax/ push her horse through the tape once. And the other time My mum saw him trying to push my other dopey TB through :roll:.
I have also seen him fiddle with the chain and paddlock around the gates with a expression saying he knows just were to get out but darn the contraption holding it shut.
