Best Odds Guaranteed on Greyhounds: How It Works

The One Feature That Costs You Nothing and Can Add 15% to Your Returns

Best Odds Guaranteed is the closest thing to a free upgrade in betting. You take a fixed price on a greyhound, the starting price turns out to be higher, and the bookmaker pays you at the better number. There’s no catch, no additional stake, and no complicated terms to navigate. It’s a one-directional safety net: you can never do worse than the price you accepted, but you can do better.

Despite being one of the most valuable features a bookmaker can offer, BOG is surprisingly underused by casual greyhound punters — partly because not all bookmakers extend it to greyhound racing, and partly because many bettors don’t fully understand how it works or how much it’s worth over time. This article fixes both problems.

How Best Odds Guaranteed Works

The mechanic is straightforward. You place a bet at a fixed price — say 5/1 — on a greyhound before the race. Between your bet and the off, the market moves. If the starting price (SP) at the time the race begins is higher than 5/1 — let’s say 7/1 — the bookmaker automatically settles your bet at 7/1 instead. If the SP is lower than 5/1, nothing changes; your bet pays at the 5/1 you took. You benefit from the upside and are protected from the downside.

This matters because greyhound markets are volatile. A six-dog race has a small number of runners and limited liquidity compared to horse racing, which means relatively modest amounts of money can move a price by several points. A dog that opens at 5/1 in the morning can drift to 8/1 by the off if it attracts less backing than expected, or shorten to 3/1 if a rush of money arrives late. Without BOG, you’re locked into whatever price you took. With BOG, you’re guaranteed the best available number between your price and the SP.

The cumulative value of BOG over a series of bets is significant. Across a full card of racing — six or more races on a standard evening — the SP will exceed your early price on at least a couple of selections, sometimes substantially. If you back three dogs at early prices and two of them drift at the off, BOG upgrades those two bets at no cost. Over weeks and months, this adds measurably to your returns — studies of horse racing BOG payouts have estimated the uplift at 10-15% of total profits, and greyhound markets, being thinner and more volatile, likely deliver a similar or larger benefit.

BOG typically applies only to bets placed at fixed odds before the off, not to bets placed at SP. If you choose to bet at starting price, BOG is irrelevant because your bet is already settled at the SP by definition. The feature is designed to reward punters who take an early view and commit to a price — which, conveniently, is exactly the behaviour that informed greyhound betting encourages.

Which Bookmakers Offer BOG on Greyhounds

Not all bookmakers that offer Best Odds Guaranteed on horse racing extend the same feature to greyhounds, and this distinction is critical. BOG on horses is near-universal among major UK operators. BOG on greyhounds is less common, and the availability can change — some bookmakers offer it during peak periods like the Derby and withdraw it for routine meetings.

Bet365 has been the most consistent major operator for greyhound BOG, applying it to all UK and Irish GBGB/IGB meetings as a standard feature. This makes Bet365 a natural first choice for punters who take early prices on greyhound racing regularly, not just on Derby night. The BOG applies automatically — there’s no opt-in required, no minimum stake, and no restriction on which races qualify.

BoyleSports also offers greyhound BOG, reflecting the bookmaker’s strong commitment to dog racing across both the UK and Irish markets. Their terms are broadly similar to Bet365’s: fixed-odds bets on GBGB and IGB meetings, applied automatically, with the SP paid if it exceeds the taken price. For punters already using BoyleSports for their Irish greyhound coverage, the BOG adds an extra layer of value.

Betfair’s sportsbook has offered greyhound BOG at various points but not always consistently. It’s worth checking the specific terms on Betfair’s promotions page before relying on it for any particular meeting. The Betfair Exchange, being a peer-to-peer platform rather than a traditional bookmaker, does not operate a BOG feature — prices on the exchange are set by other bettors, and there’s no SP mechanism in the same sense.

Paddy Power, William Hill, Ladbrokes, and Coral have all offered greyhound BOG at times but have also withdrawn it or limited it to specific events. The pattern is that these operators are more likely to activate greyhound BOG around the Derby and other major competitions than for day-to-day racing. If you’re primarily interested in BOG for Derby week, check each bookmaker’s promotions page in the days before the competition — Derby-specific BOG offers frequently appear as part of the event’s promotional push.

Why BOG Matters Most on Derby Night

The Greyhound Derby final produces some of the largest price movements in the greyhound betting calendar. Public interest is at its peak, casual money floods the market, and prices on individual dogs can move by several points between the morning and the off. A dog that opens at 6/1 might go off at 10/1 because the public money concentrated on the favourite instead. Without BOG, you’re stuck at 6/1. With it, you get 10/1 — a 67% increase in potential profit on the same stake.

This effect is amplified across a full Derby night card. If you’re betting on heats as well as the final, you might have four or five bets where the SP differs from your taken price. On a volatile evening, BOG could upgrade two or three of those bets, adding a meaningful increment to your overall return. The feature is free, and the value is real — there’s no rational reason to bet on Derby night without it active on at least one of your bookmaker accounts.

One practical application: if you’ve identified a dog at 8/1 in the morning and you believe the price is fair, take it with a BOG bookmaker rather than waiting to see if it drifts. If the dog shortens to 5/1 by the off, your 8/1 stands. If it drifts to 12/1, you get 12/1. The BOG effectively gives you a free option on any price movement in your favour, which is particularly valuable in the thin, reactive markets that characterise Derby night.

Free Insurance You Should Never Bet Without

Best Odds Guaranteed is the rare promotional feature that delivers genuine, quantifiable value without requiring you to change your betting behaviour. You don’t need to bet more, bet differently, or jump through hoops. You just need to make sure you’re placing your greyhound bets with a bookmaker that offers BOG — and if you’re not, you’re leaving money on the table every time the SP exceeds the price you took.

Before Derby week, confirm which of your bookmaker accounts have greyhound BOG active. If none of them do, open an account with one that does — Bet365 and BoyleSports are the most reliable options at the time of writing. The five minutes it takes to set up the account could be worth more to your bottom line than any amount of form study, because BOG adds value to every bet you place, not just the ones you get right.
