Either way, my dog now stinks.... 
I've just been out in the garden to find out what my dog was so keen to investigate to find her chasing either a ferret or polecat around whilst it made high-pitched screeching or 'crawing' sounds. After a couple of laps of the veggie patch it escaped through the fence.
She came in after satisfying herself that it had gone, and she utterly stinks. I'm not bathing her at this time, so I've locked her downstairs for the night and will dunk her in the morning if it hasn't evaporated by then.
I live in a rural area on the English / Welsh border in South Cheshire / North Shropshire, surrounded by fields.
As it was being pursued at speed around the garden, I couldn't examine it closely - but does anyone know if there's any way I'd be able to definitively decide if it was an escaped / feral ferret or a polecat? I was always under the impression that the latter were incredibly rare.
