A new start-up company called Whistle is launching a smart pendant that tracks physical activity levels and sleep patterns in dogs.
"Whistle was inspired by my love of dogs," said co-founder Ben Jacobs at the company's San Francisco office.

"We're introducing a window into their lives and creating a way for owners and veterinarians to take a preventative approach to our pets' health."
Whistle devices attached to dog collars or harnesses use movement-sensing accelerometers to track activity and even how well a pet is sleeping, then relay the information wirelessly to smartphones or Wi-fi hotspots.
An online database built in collaboration with researchers and veterinary groups allows individual dog activity patterns to be scrutinised for hints that something may be amiss.
Data collected by the devices is fed to a free application tailored for Apple mobile devices. A version of the app will be released for Android-powered gadgets later this year, according to Jacobs.
