Not normally but I arrived at yard tonight to a very sorry for herself lonely and absolutely filthy b1 on her own in wrong paddock. No fence damage so don't know how.
Yes, my old pony did this on the yard we got her from. She always forgot until too late that she didn't actually like the horses in the paddock she'd break into
She didn't need the rug with me, I rarely put a charger on my fences. She'd humour me and be polite for a week or two, and then break out
