site during racing. The greyhounds require microchipping, annual vaccinations against distemper, infectious canine hepatitis, parvovirus, leptospirosis, and a vaccination to minimize outbreaks of diseases such as kennel cough. All greyhounds in the UK must pass a pre-race veterinary inspection before being allowed to take part in that race. The racing industry (in several countries) actively works to prevent the spread of doping cases. Attempts are being made to recover urine samples from all greyhounds in a race, not just the winners. Greyhounds from which samples cannot be obtained for a certain number of consecutive races are subject to being ruled off the track in some countries. Violators are subject to criminal penalties and loss of their racing licenses by state gaming commissions and a permanent ban from the National Greyhound Association. The trainer of the greyhound is at all times the "absolute insurer" of the condition of the animal. The trainer is responsible for any positive test regardless of how the banned substance has entered the greyhound's system. Retirement Generally, a greyhound's career will end between the ages of four and six – after the dog can no longer race, or possibly when it is no longer competitive. The best dogs are kept for breeding and there are industry-associated adoption groups and rescue groups that work to obtain retired racing greyhounds and place them as pets. In the United Kingdom, the Greyhound Board of Great Britain (GBGB) has introduced measures to locate where racing greyhounds reside after they have retired from racing and as from 2017 records have been available to the public. Several organizations, such as British Greyhounds Retired Database, Greyhound Rescue West of England, Birmingham Greyhound Protection, GAGAH, Adopt-a-Greyhound and Greyhound Pets of America, and the Greyhound Trust try to ensure that as many of the dogs as possible are adopted. Some of these groups also advocate better treatment of the dogs while at the track and/or the end of racing for profit. In recent years the racing industry has made significant progress in establishing programs for the adoption of retired racers. In addition to actively cooperating with private adoption groups throughout the country, many race tracks have established their own adoption programs at various tracks.
