Wire in the way

My sweet and beautiful Mijne, our Goofball and most physical boy, had me scared today. On our 23 acres there are a lot of wired fences that are left by the previous owners who put it there for cattle etc. Sometimes there is also barbed wire. Today Mijne jumped over wire that he wasn't supposed to and i called him. Instead of jumping over the same spot back to me, he tried to jump over a higher part of the fence and got 'hanging' on some wire. He yelped and I first thought it was barbed wire. But luckily it was only wire without the 'barbed' and there was no harm done.
