Racing lineage

All racing greyhounds registered with the National Greyhound Association have identifying tattoos in both ears.  Litter mates have the same, five-digit tattoo in their left ears. The tattoo in the right ear designates the month, year and order of tattooing.  For example: 126B indicates that the dog was born in December 2016 and was the second in the litter to be tattooed.

Most adoption groups provide this information when the greyhound is adopted.  Often, they provide the racing name of the dog as well.

GreyhoundData.com and TrackInfo.com are repositories of information concerning racing greyhounds. With the information described above, information about an individual greyhound's racing history and lineage can be found.
