A study by a group of researchers started looking at ways to better care for dogs that are left alone for extended periods of time.

This involved equipping dogs with hi-tech collars containing accelerometers. The researchers installed video cameras in the dog owners’ homes to match the data from the collars to the behaviours of the specific dogs. After a month of this research they were able to code movement patterns for 17 dog activities including barking, chewing, drinking and shivering. Without the use of the cameras, the researchers were able to recognise them with 68.6% accuracy.

Although this research started as a way of finding ways to take better care of dogs left home alone, it began to prove other uses. These collars that identify dogs’ behaviour could help people recognise early warning signs of elderly people who are struggling to cope at home.

Nils Hammerla, one of the researchers said: "A dog’s physical and emotional dependence on their owner means that their wellbeing is likely [to] reflect that of their owner and any changes such as the dog being walked less often, perhaps not being fed regularly, or simply demonstrating ‘unhappy’ behavior could be an early indicator for families that an older relative needs help."

The technology could also one day be used as a distress signal for emergencies – so people can track unusual behaviour in the dog, which could indicate that something is wrong with the owner.

The accelerometer collar is a great idea for those who live on their own, with only their pet to keep them company on a daily basis. So if there was ever to be an accident or problems with health, it’s comforting to know that man’s best friend will be there for them, as their personal distress signal and constant companion.
