Greyhound Betting Glossary

The Language of the Dogs

Greyhound racing has its own vocabulary—a mixture of betting terminology shared with horse racing, track-specific jargon unique to the dogs, and informal slang that has accumulated over decades of punting. Some terms are self-explanatory. Others carry specific technical meanings that differ from their everyday usage. This glossary covers the words and phrases you’ll encounter in race cards, form guides, tipster columns, and bookmaker markets, defined in the context of UK greyhound racing.

A

Accumulator — A bet combining multiple selections into a single wager. All selections must win for the bet to pay out. Returns from each winning leg roll into the next, producing larger potential payouts at higher risk.

Ante-post — A bet placed on a future event before the final runners are confirmed. Stakes are lost if the selection doesn’t participate. Prices are typically longer than race-day odds to compensate for the additional risk.

All in, run or not — The standard ante-post condition meaning no refund is given if your selection is withdrawn from the event.

Advised price — The odds at which a tipster recommends backing a selection, recorded at the time of the tip.

B

BAGS — Bookmakers’ Afternoon Greyhound Service. The system of afternoon greyhound meetings scheduled primarily for betting shop coverage. BAGS meetings run at multiple tracks throughout the day.

Backer — A person who bets on a selection to win.

Baulked — When a dog’s run is impeded by another dog, typically through crowding on a bend. Race comments noting “baulked first bend” indicate the dog’s finishing position may not reflect its true ability.

Best odds guaranteed — A bookmaker promotion that pays out at the higher of the odds taken or the starting price, whichever benefits the punter. Abbreviated as BOG.

Blanket finish — A race where multiple dogs cross the line separated by very short distances, making the result difficult to judge visually.

BOG — See best odds guaranteed.

Bookmaker margin — See overround.

Box — Another term for a starting trap. Dogs are loaded into numbered boxes before the race begins.

Bumped — Physical contact between dogs during a race, typically at bends. Can affect finishing positions and is noted in race comments.

C

Card — The full programme of races at a meeting. Also refers to the race card, the document listing runners, trap draws, and form for each race.

Cash out — A feature allowing punters to settle a bet before the event concludes, at a value determined by the current market. Available on selected bookmaker platforms.

Checked — When a dog slows or adjusts its stride to avoid a collision. Less severe than being baulked, but can affect finishing position.

Closer — A dog that typically runs from behind, relying on late pace rather than early speed. Closers need clear running in the final stages to be effective.

Combination forecast — A forecast bet covering multiple permutations of two or more dogs finishing first and second. Costs more than a straight forecast but covers more outcomes.

Combination tricast — A tricast bet covering all possible orders of three selected dogs finishing first, second, and third. Requires six permutations per set of three selections.

Connections — The people associated with a dog: owner, trainer, and kennel staff.

Crowded — When a dog loses ground due to multiple runners converging in the same space, typically at the first bend.

D

Decimal odds — An odds format expressing total return per unit staked. Odds of 4.00 return £4 for every £1 wagered, including the original stake. Widely used on betting exchanges and European platforms.

Dividend — The payout declared on a tote or pool bet after the race. Expressed as a return per £1 unit staked.

Double — An accumulator containing exactly two selections. Both must win for the bet to pay out.

Draw — The trap number allocated to each dog for a race. Also used informally to describe the trap allocation process. See also seeding.

Drift — When a dog’s odds lengthen, indicating less money is being bet on it or more money is flowing toward other runners. A “drifter” is a dog whose price has moved outward.

Dutch — To back multiple selections in the same race at calculated stakes to produce an equal profit regardless of which selection wins.

E

Each way — Two bets in one: a win bet and a place bet at reduced odds. In greyhound racing, place terms typically pay at one-quarter the odds for finishing in the first two.

Early pace — A dog’s speed in the opening section of a race, from traps to the first bend. Early-pace dogs are sometimes called “front-runners.”

Early price — Odds offered before the final pre-race market, typically available from the morning of a meeting. Taking an early price locks in your odds ahead of market movement.

Evens — Odds of 1/1. A winning bet at evens doubles your stake. In decimal format, evens equals 2.00.

Exacta — Tote term for a forecast bet: selecting the first and second finishers in the correct order.

Exchange — A betting platform where punters trade bets with each other rather than against a bookmaker. Betfair and Smarkets are the main UK exchanges.

F

Favourite — The dog with the shortest odds in a race, considered most likely to win by the market.

Fixed odds — Odds that are agreed at the time the bet is placed and don’t change regardless of subsequent market movement.

Flutter — Informal British term for a bet, typically a small or casual one. “Having a flutter on the dogs.”

Forecast — A bet requiring the punter to predict the first and second finishers in a race. A straight forecast requires the correct order; a reverse forecast covers both possible orders.

Form — A dog’s record of past performances, including finishing positions, times, and grades. Form figures are displayed on race cards as a sequence of numbers representing recent results.

Fractional odds — The traditional UK odds format expressed as a fraction. Odds of 5/1 mean five pounds profit for every one pound staked.

Front-runner — A dog that typically leads from the traps and attempts to maintain its advantage throughout the race. Front-runners benefit from inside trap draws at tracks with early first bends.

Full card — A complete programme of races at a meeting, typically consisting of twelve to fourteen races.

G

GBGB — Greyhound Board of Great Britain. The regulatory body for licensed greyhound racing in the UK, responsible for rules of racing, integrity, and welfare standards.

Going — The condition of the track surface. Greyhound tracks are typically sand-based, with conditions described as normal, slow, or fast depending on moisture levels and weather.

Graded race — A race where dogs are grouped by ability, using a letter-number system. A1 is the highest standard grade; lower numbers indicate higher quality. Grades ensure competitive racing between dogs of similar ability.

Grader — The official responsible for assigning dogs to appropriate grades based on recent performance.

Green sheet — Informal term for the printed race card or form guide, historically printed on green paper at some tracks.

H

Hare — The mechanical lure that dogs chase during a race. The hare runs on a rail around the inside or outside of the track, depending on the venue.

Handicap race — A race where dogs start from staggered positions based on assessed ability, designed to give every runner an equal chance. Less common than graded races in UK greyhound racing.

Head — A unit of measurement for the distance between dogs at the finish. A “short head” is the smallest measurable margin.

Heat — A preliminary round of a knockout competition. Dogs must win or qualify from their heat to progress to the next stage.

I

Implied probability — The probability of an outcome as suggested by the odds. Calculated by dividing one by the decimal odds. Odds of 4.00 imply a 25% probability.

In-play — Betting during a live event. Limited in greyhound racing due to the short race duration, but offered by some bookmakers on selected races.

Inside runner — See railer.

J

Jackpot — A tote bet requiring the winner to be selected in every race of a nominated sequence. Jackpot pools roll over when unsolved, creating large potential payouts.

Jolly — Slang for the favourite in a race. “The jolly” is the most fancied runner in the market.

Juice — Informal term for the bookmaker’s margin or overround. See also vig.

K

Kennel — The training establishment where a greyhound is housed and prepared for racing. Each kennel is managed by a licensed trainer.

Kennel money — Bets placed by or on behalf of a dog’s connections, often considered informed money that may indicate confidence in the selection.

L

Lay — To bet against a selection. On a betting exchange, laying a dog means you profit if it loses. The layer accepts the backer’s stake and pays out if the selection wins.

Length — A unit of distance for measuring margins between finishers. One length is approximately the length of a greyhound’s body.

Level stakes — A staking strategy where the same amount is wagered on every selection regardless of odds or confidence. Used as a standard for measuring tipster or system performance.

Liability — The maximum amount a layer stands to lose on an exchange bet if the selection wins.

Live odds — Odds that update in real time as the market moves approaching race time.

M

Maiden — A dog that has not yet won a race. Maiden races are restricted to dogs without a victory on their record.

Market — The collective set of odds available on a race from one or more bookmakers.

Market mover — A selection whose odds have changed significantly, indicating notable betting activity. A shortening price is a “steamer”; a lengthening price is a “drifter.”

Middle tracker — A dog that naturally runs in the middle of the track rather than hugging the rail or running wide. Middle trackers are typically seeded into traps three or four.

Monkey — Slang for a £500 bet.

Morning price — The initial odds offered by a bookmaker on the morning of a meeting, before the market has been shaped by betting activity.

N

NAP — A tipster’s strongest selection of the day. From “Napoleon,” the highest-value card in the card game of the same name.

Neck — A margin of approximately half a length between finishing dogs.

Non-runner — A dog that is withdrawn from a race before it starts. In standard race-day betting, stakes on non-runners are refunded. In ante-post betting, they are not.

Nap hand — A set of confident selections across multiple races.

O

Odds-against — Any price longer than evens, where the potential profit exceeds the stake. Odds of 3/1, 5/2, or 7/4 are all odds-against.

Odds-on — Any price shorter than evens, where the potential profit is less than the stake. Odds of 4/5, 1/2, or 8/11 are odds-on.

Off — The moment the race starts, when the traps open and the hare is running. “At the off” means at race start time.

Open race — A race not restricted by grade, open to dogs of any ability level. Open races typically attract the strongest fields and are associated with prestige competitions.

Outsider — A dog considered unlikely to win, reflected in long odds. Also informally called a “rag” or “no-hoper.”

Overround — The percentage by which the sum of all implied probabilities in a market exceeds 100%. A six-dog market with an overround of 118% means the bookmaker has an 18% built-in mathematical edge. Also called the margin, vig, or juice.

P

Pari-mutuel — The formal term for pool or tote betting, where all stakes go into a pool and dividends are calculated after the event.

Photo finish — When the margin between dogs at the finish is too close to determine visually, requiring the official photo-finish camera to separate runners.

Place — Finishing in a position that qualifies for a payout on a place or each-way bet. In six-runner greyhound races, first and second typically count as “placed.”

Placepot — A tote bet requiring a placed selection in every race of a nominated sequence.

Pool — The total amount of money wagered on a particular tote bet type for a single race. The pool is divided among winners after the operator’s takeout is deducted.

Price — Informal term for odds. “The price” of a dog is its current odds.

Punter — A person who bets. The standard British term for a bettor.

R

Race card — The document listing all information about a race: runners, trap draws, form figures, trainer, recent times, and grade. The primary tool for pre-race analysis.

Rag — Slang for an outsider with little perceived chance of winning.

Railer — A dog that naturally runs close to the inside rail. Railers are typically drawn in traps one or two and benefit from the shortest route around bends.

Reserve — A substitute dog that runs if one of the originally carded runners is withdrawn close to race time.

Return — The total amount paid back to a winning punter, including the original stake.

Reverse forecast — A forecast bet covering both possible finishing orders of two selected dogs. Costs twice a straight forecast but wins if the two dogs finish first and second in either order.

ROI — Return on investment. The percentage profit or loss relative to total stakes. An ROI of +5% means five pounds profit for every hundred pounds staked.

Rollover — When a tote jackpot pool is not won and carries forward to the next qualifying meeting, increasing the pool size.

S

Sectional time — The time taken for a dog to complete a specific section of the race, typically the run to the first bend. Sectional times reveal early pace and can indicate ability more accurately than overall finishing time alone.

Seeding — The process of allocating trap draws based on a dog’s running style. Railers are seeded to inside traps; wide runners to outside traps. Designed to minimise interference and produce fairer racing.

SIS — Sports Information Services. The media company that broadcasts the majority of UK and Irish greyhound racing to bookmakers and betting platforms.

SP — See starting price.

Split time — See sectional time.

Sprint — A race over the shortest available distance at a track. Typical sprint distances range from 210 to 300 metres depending on the venue.

Stake — The amount of money wagered on a bet.

Standard distance — The most commonly raced distance at a particular track. For many UK tracks, this is 480 metres.

Starting price — The official odds at which a dog starts a race, determined at the moment the traps open. Abbreviated as SP. Used to settle bets placed without taking a fixed price.

Steamer — A selection whose odds shorten rapidly as money flows onto it. A steamer moving from 6/1 to 3/1 indicates significant market confidence.

Stewards’ enquiry — An official investigation into an incident during a race. May result in a revised finishing order, a fine, or no action.

Straight forecast — A bet on two dogs to finish first and second in a specific order.

Strike rate — The percentage of bets that produce a winning outcome. A strike rate of 20% means one winner in every five selections.

T

Takeout — The percentage deducted from a tote pool before dividends are calculated. The tote equivalent of a bookmaker’s overround.

Tissue — A bookmaker’s initial pricing assessment for a race, created before public betting begins. The tissue forms the basis for morning prices.

Tote — Pool betting operated at UK tracks and online. All stakes go into a shared pool, with dividends calculated after the operator’s deduction.

Trap — The numbered starting box from which a dog begins a race. UK greyhound races use six traps, coloured red, blue, white, black, orange, and black-and-white stripes for traps one through six respectively.

Trap bias — The statistical tendency for certain traps to win more or less frequently than expected at a particular track and distance. Caused by track geometry, bend positioning, and running rail proximity.

Treble — An accumulator containing exactly three selections. All three must win for the bet to pay out.

Tricast — A bet requiring the punter to predict the first, second, and third finishers in the correct order. Offers large potential returns due to the difficulty of the task.

Trifecta — Tote term for a tricast bet.

Trial — A non-competitive run used to assess a dog’s fitness, speed, or suitability for a particular track. Trial results are not always publicly available but may influence connections’ confidence.

U

Unmatched bet — An exchange bet that has been offered but not yet accepted by a counterparty. Unmatched bets are cancelled if still open when the race begins.

Unraced — A dog that has not yet competed in an official race. Unraced dogs may have trial form but no public race record.

V

Value — When the odds offered on a selection exceed the true probability of that outcome occurring. The fundamental concept behind profitable long-term betting.

Vig — Short for vigorish. Another term for the bookmaker’s overround or margin. See also juice.

Void — A bet that is cancelled and the stake returned. Typically occurs when a selection is a non-runner in standard race-day betting.

W

Wager — Formal term for a bet.

Weight of money — The volume and direction of betting activity on a selection. Heavy weight of money shortens odds; lack of interest allows them to drift.

Wide runner — A dog that naturally takes a wide path around bends rather than hugging the rail. Wide runners are typically seeded into traps five or six to minimise interference with railers.

Win bet — The simplest bet type: selecting the dog that will finish first. The stake is lost if the dog finishes in any other position.

Win pool — The tote pool for win bets on a single race.

Withdrawal — The removal of a dog from a race before the start. See also non-runner.
