i think you might mean bedlington hound lad,it would be a bedlington terrier/greyhound cross.a lurcher.
Would that cross be called a belton hound though? Because the fella thats selling it is calling the dog a belton hound. i thought he meant the color was belton but he has said its the breed of dog. Thanks anyway mate, may ask him for a photo of it!
if the colour you mean is a bit like the mottle on a german shorthaired pointer i would agree with that.
