Wearable technology has gone to the dogs. No, really, Voyce has designed a wearable device for dogs that measures a range of key vital signs like heart rate and respiratory rate. The device also tracks the dog's sleeping patterns and activity levels. Voyce's online tool that displays the data also provides a library of information if you have questions about your dog's vital signs. The collar is lightweight and not much heavier or bigger than a normal collar. Unfortunately, it doesn't say what your dog is thinking, but our guess is that he just wants another treat or go for a walk.
