I mentioned having a rusty dog fence.
WE did, however, have horse panel when I was a kid to fence in two goats. We fenced in about an acre back then, and I remember the fence being more shiny looking and not galvanized, but it wasn't coated with plastic, that's for sure.
It did last well, a completely different level of quality vs. the light duty dog fence installed in my back yard.
The goats rubbed it and tested it, too, and it stood up to that for years, and stood up to us moving their fenced area - they killed anything that didn't have dense hard bark, thus the desire to move their fence and let them clear underbrush.
