AKC® has a new competitive sport, aptly named Fast CAT (Coursing Ability Test). The Fast CAT is basically a timed, 100 yard dash. The time is recorded in 100ths of seconds and is then converted to miles per hour (MPH). In fairness to all sizes of dogs smaller dog receive a multiplier to get a final number of points.
This timer app may be used standalone, or, more practically, with IR beam break gates provided by Agility Dog Technologies www.AgilityDogTech.com
