A horse's pedigree certainly says a lot about how much success he or she might endure during their racing career, and of the top contenders in the 2012 Preakness Stakes, some have been sired by superb thoroughbreds.
It's no secret that having athletic parents increases the chances of a son or daughter becoming a dominant player in whatever sport they choose.
The same goes for horse racing, as elite thoroughbreds have gone on to breed some big-time winners.
That being said, here are a few horses in the 137th edition of the Preakness Stakes that have been sired by big winners.
Teeth of the Dog
Despite not running in the Kentucky Derby, Teeth of the Dog is still a great horse.
Sired by Bluegrass Cat, Teeth of the Dog has a strong pedigree that needs to be taken seriously. The colt may not win it all, but don't be surprised if he makes a strong push.
Bluegrass Cat took first place in nearly half of his races. In addition to that, Bluegrass Cat finished second place in the 2006 Kentucky Derby, as well as a second place finish at the 2006 Belmont Stakes.
Also sired by Bluegrass Cat, Pretension is another horse to watch out for in the Preakness.
The big favorite in the Preakness, Bodemeister was so close to contending for a Triple Crown but lost in the closing seconds of the Kentucky Derby to I'll Have Another.
Sired by Empire Maker, Bodemeister has garnered a great deal of hype, and rightfully so. Prior to the Triple Crown series, Empire Maker took first place in its two races, the Wood Memorial and the Florida Derby.
In the 2003 Kentucky Derby, Empire Maker was a big contender but ended up finishing in second. He didn't ride in the Preakness Stakes but did participate in the 2003 Belmont Stakes and won.
Bodemeister has a strong pedigree and that's a big reason he's thrived in his career.
Went the Day Well
Before competing in the Kentucky Derby, Went the Day Well won it's previous two races. In the Derby, the colt took fourth place, which is a great indication he'll thrive once again this weekend.
Sired by Proud Citizen, Went the Day Well has a good pedigree, which was helped him succeed in his career.
Proud Citizen had several ups and downs during his career, but he took charge and excelled in the big races, something that will work in Went the Day Well's favor.
A second place finish in the 2002 Kentucky Derby, a third place finish at the 2002 Preakness and then a fifth place finish at the 2002 Belmont Stakes is a great sign. Proud Citizen raced well when it mattered most, on the big stage, which is good news for Went the Day Well.
