Greyhound Betting Glossary: 60+ Terms Every Punter Must Know

Speaking the Language

Greyhound racing has its own vocabulary. Some terms are shared with horse racing, others are unique to the dogs, and a few are specific to the UK betting market. If you have ever read a race card or a tipster’s analysis and hit a word you did not recognise, this glossary is your reference. The terms are arranged alphabetically and defined in plain language with practical context for how they apply to betting — particularly forecast betting.

A to F

Accumulator. A single bet that combines two or more selections across different races. All legs must win for the bet to pay. A forecast accumulator links forecast bets from multiple races, with the return from each winning leg rolling into the next.

Ante-post. A bet placed well in advance of a race, typically on major events like the English Greyhound Derby. Ante-post bets usually offer longer odds but carry the risk of losing your stake if the dog is withdrawn before the event.

Best Odds Guaranteed (BOG). A bookmaker offer where you receive the higher of the price you took or the starting price. Uncommon for greyhound forecasts but available for win bets at some firms.

Bumped. When a dog makes physical contact with another dog during a race, causing it to lose momentum or position. Race comments use “bumped” to explain why a dog finished below expectations.

Checked. When a dog is forced to slow down or change direction to avoid another dog. Being checked at the first bend is a common cause of underperformance relative to form.

Combination forecast. A forecast bet covering all possible first-and-second permutations of three or more selected dogs. Three dogs produce six bets; four dogs produce twelve.

Computer Straight Forecast (CSF). The industry-standard formula used to calculate the return on a bookmaker forecast bet. The CSF uses the starting prices of the first and second-placed dogs to generate a fixed dividend per pound staked.

Crowded. When a dog is squeezed between other runners, particularly at the bends. Crowding causes loss of momentum and finishing position.

Dead heat. When two or more dogs finish a race in the same position simultaneously, as determined by the photo-finish. Forecast bets involving dead-heated dogs are settled at half the normal dividend.

Dividend. The payout per unit stake on a winning forecast or tote bet. A forecast dividend of £25 means a £1 bet returns £25.

Double. An accumulator with two legs. A forecast double links two forecast bets from two different races.

Each-way. A bet placed on a dog to win or finish second. In greyhound racing, each-way terms are typically 1/4 the odds for a place in a six-dog field. Not directly applicable to forecasts but relevant to wider betting terminology.

Exacta. The American term for a forecast — predicting the first two finishers in exact order. Rarely used in UK greyhound betting but encountered in international contexts.

Form. The record of a dog’s recent racing results, typically the last six finishing positions. Form figures are the primary data source for forecast analysis.

Forecast. A bet requiring the selection of the first two finishers in a race in the correct order. The core bet type covered by this site.

G to N

GBGB. Greyhound Board of Great Britain. The regulatory and governing body for licensed greyhound racing in England, Scotland, and Wales (GBGB). GBGB sets the rules, oversees welfare standards, and administers the grading system.

Going. The condition of the racing surface. Greyhound tracks do not publish formal going descriptions like horse racing, but conditions vary with weather — wet sand is slower than dry sand.

Graded race. A race where all six runners are assigned from the same grade level, ensuring competitive balance. Graded races make up the majority of the UK greyhound racing calendar.

Grading. The system that assigns dogs to race categories (A1 through A11 and beyond) based on their recent times at a specific track. Higher-numbered grades indicate slower dogs.

Hare. The mechanical lure that the dogs chase around the track. UK tracks use either an inside hare (running along the inside rail) or an outside hare (running on a rail outside the track). The hare type affects running dynamics.

In season. Refers to a bitch (female greyhound) being in her heat cycle. Bitches in season are withdrawn from racing, and their return often requires a run or two to regain race fitness.

Kennel. The training establishment that prepares and manages greyhounds for racing. Used interchangeably with “trainer” in common parlance.

Lay. To bet against a selection — predicting that a dog will not win. Available on betting exchanges but not at traditional bookmakers.

Level stakes. A staking method where the same amount is wagered on every bet, regardless of confidence or odds. Level-stakes profit or loss is the standard measure of tipster and bettor performance.

Middle runner. A dog that runs between the rail and the outside on the bends, typically one or two lanes off the fence. Middle runners are versatile but prone to interference in crowded fields.

Non-runner. A dog that has been withdrawn from a race after the field was declared. Non-runners trigger specific settlement rules for forecast bets, typically voiding the affected selections.

O to S

Open race. A race that sits outside the standard grading system. Open races attract dogs based on ability, qualification, or invitation rather than grade, often producing wider ability ranges in the field.

Overround. The bookmaker’s built-in profit margin, calculated by summing the implied probabilities of all runners in a market. An overround of 120% means the total implied probability exceeds 100% by 20 percentage points.

Parimutuel. The pool-based betting system used by the tote, where all stakes are pooled and the dividend is calculated by dividing the pool among winning tickets after deducting commission.

Patent. A full-coverage bet on three selections: three singles, three doubles, and one treble — seven bets in total. A forecast patent provides partial returns even if not all three legs win.

Photo finish. The system used to determine finishing positions in close races. A photo-finish camera captures the dogs crossing the line, and the judge uses the image to declare the official result.

Railer. A dog that naturally runs along the inside rail, saving ground on the bends. Railers perform best from inside trap draws (Trap 1 or 2).

Reserve. A replacement dog that fills a vacant trap when the original entrant is withdrawn. The reserve wears the same colour jacket and runs from the same trap position.

Reverse forecast. Two straight forecast bets on the same pair of dogs, covering both possible finishing orders. A reverse forecast costs twice the unit stake.

Rule 4. A deduction applied to winning bets when a runner is withdrawn from a race after the market has formed. Rule 4 deductions reduce the payout to account for the removed runner’s implied probability. More common in horse racing; in greyhound forecasts, the affected bet is typically voided rather than reduced.

Sectional time. The time recorded for a specific segment of a race (e.g., trap to first bend, first bend to second bend). Sectional times reveal early pace, sustained speed, and closing ability that overall times cannot distinguish.

SP (Starting Price). The official odds at the moment the race begins. SP is the basis for CSF calculation and is used to settle bets placed at “starting price” rather than at a fixed early price.

Straight forecast. A single bet on two dogs to finish first and second in a specific order. The simplest and cheapest forecast bet type.

T to Z

Tattersalls Rules. The set of rules governing the settlement of bets in UK horse and greyhound racing. Tattersalls Rules cover non-runners, dead heats, void bets, and other settlement scenarios.

Tote. The pool-betting operator in UK racing. The tote aggregates all stakes on a given market and distributes the pool (minus commission) among winning ticket holders. Tote forecast dividends differ from CSF dividends because they are driven by pool distribution rather than starting prices.

Trap. The starting box from which a greyhound begins the race. UK greyhound races use six traps, numbered 1 to 6, each with a specific colour: red (1), blue (2), white (3), black (4), orange (5), black and white stripes (6).

Trap bias. A persistent statistical tendency for certain traps to win more often than expected at a given track, caused by track geometry — particularly the distance and angle of the first bend relative to the traps.

Treble. An accumulator with three legs. All three selections must win for the bet to pay.

Trial. A non-competitive race run for timing and conditioning purposes. Trial results appear on the race card with a “T” marker and are used by trainers to prepare dogs for competitive entries or test them at unfamiliar tracks.

Tricast. A bet requiring the selection of the first three finishers in exact order. Harder than a forecast (120 possible combinations vs 30) but pays significantly higher dividends.

Void. A bet that is cancelled, with the stake returned to the bettor. Forecast bets are voided when a selected dog is a non-runner with no reserve replacement.

Weight. The dog’s racing weight in kilograms, listed on the race card. Weight changes between runs can indicate fitness shifts.

Wide runner. A dog that naturally runs wide of the rail on the bends, covering more ground but avoiding traffic. Wide runners perform best from outside traps (Trap 5 or 6).

Using the Language

These terms are not just vocabulary — they are the shorthand of an analytical framework. Each one represents a concept that informs how races unfold and how bets are settled. When a tipster writes “CSF of £28 after Trap 2 railer led first bend with Trap 6 wide runner running on for second,” every term in that sentence carries weight. Knowing the language lets you read the analysis, interrogate the logic, and make your own informed decisions about where to place your forecast stake.
