Nova Scotia winters SUCK. They are cold& miserable. Trust me ..I live in them LOL! I don't know many Tollers personally but the few I've met, have been sweet little dogs. They seem fun but I can't comment on their hunting ability at all. Some are really driven, some are meh.
-As a side note, my smooth Vizsla will jump in the water& swim for hours on end in the ocean in January. She doesn't shiver until she stops moving but a quick towel off& a coat on her, she's good for another few hours running in the snow.. don't know about a wirehair though!
