Animal racing, specifically horse and greyhound racing, isn't just about the power and precision of the animal. For example, the greyhound trainer also plays an important role in the odds of a race. Greyhounds trained by seasoned trainers always have greater odds of winning. In addition, bettors must also consider a dog's family lineage and how that may affect its performance.
A competing dog's age and fitness levels also affect the odds, just as they do humans. For example, adding new dogs to the lineup that are young and at their prime often pushes favorites down the pecking order. The positive part about dogs in racing is that they don't need too long of a break between races, allowing them to take part in more. This means bettors can set multiple bets on specific greyhounds while on a consistent run of form.
Odds for how a race may unfold are offered on a greyhound sportsbook up until the race starts. Bettors can pick their desired odds and place a wager on them. Something to note is that there is no distinction between odds that appear differently (American, UK, and European).
Differentiation of a money line, decimal, or fraction doesn't necessarily indicate winners will get dissimilar amounts. On the other hand, some odds display the amount a player stands to win as part of their stake, while others do not display their stake.
However, odds may vary between betting sites, so it's important for a bettor to do their research. At the end of the day, the difference is seldom meaningful unless one is betting a fortune.
