The price discrepancy in these types of market always fascinates me and sometime you can find a price which is way out
Now I'll admit that I haven't done much research into this (for "not much" read "any") but does Dog not seem a bit overpriced @ 7/1 with Ladbrokes & Sporting Bet
Hills have priced dog @ 6/4 which is a bit more realistic IMO
Obviously I wouldn't be tying up my Cheltenham war chest in this bet or anything but it might be worth a spare tenner!
