If I were you I'd contact the Tofield auction house IMMEDIATELY as they're a well known slaughter sale and also contact any other area feed lots, broker yards, and near by slaughter houses to submit photos and other proof of ownership. Advise the RCMP to do the same, though Bouvry has been well known not only to not slaughter horses correctly, but not verify ownership either :(
Wow--you always have the thought in the back of your mind that one of your horses might get out and get away, or someone might like one of your horses and try to take it, but ALL NINE!?! I would have been freaking out!! Thank goodness they were found safe!
