Red-hot competition at the annual Casterton Working Dog Auction on Sunday helped to offset the bitterly cold conditions, with the average sale price jumping 16% on last year, at $8,850 per dog - with the “top dog” hitting $27,000. Interfaced with AuctionsPlus for the second year, this year's sale utilized pre-bidding, along with a live interface on sale day - allowing online buyers the opportunity to place bids in the lead up to, and on sale day.
