Keeping records on various aspects of dogs' lives can be an important part of their overall care, whether those records are for medical care, feeding, breeding, training, or exercise. Recording the details can help improve health, condition, and performance in dogs, and will provide useful information for a dog's lifetime and beyond.
Hetta Huskies, part of Finland's Center for Arctic and Polar Exploration (CAPE Lapland), has developed record-keeping systems for many different aspects of a dog's life, including running records which detail when and for how long each dog is exercised. Learn more at their website:
