Im really surprised that the lads who stalk venison rely on some of the traditional dogs about,that cost a fortune,the best dog ive ever witnessed,ive seen a few,working venison and following scent and blood trails is a Bedlington terrier,working type.Excellent nose,highly trainable,plus a good household pet.
I'd have to agree with you, I have a bedlington whippet x mainly for ferretting but I have found she is very good at following up deer. She has an awesome nose (shows the spaniels up on the local shoot) the only thing I haven't tried to train her to bay when she finds. When its dark I just put a collar with a light and a bell on it, give her her head and she never lets me down.
She'll stay to heel and wait if I take her stalking but normally leave her in the truck and get her out after that late shot on the edge of a wood or in a crop.
