My dear friend legged it up to the house, ran in the door and screamed her lungs out. The yard owner's boyfriend had to lift Ruby off the gate.
The vet came, and had to sew up her inside leg. The stab was 4 inches deep. She also had a latex drain sew in.
Before the vet arrived
She's doing fine now- eating and bumbling around her field (she doesn't do stables) and stitches are still in.
NEVER in your life get gates with a protuding pole (e.g. ¬) they are stupidly dangerous.
