LOS ANGELES (AP) — You can use wearables with GPS to keep track of wandering dogs. Others help you track animals’ physical activity.

Now, two companies have the latest in wearable pet technology — collars that can check for a fever, monitor pulse and respiration, and even indicate if your pet is in pain.

PetPace, based in Burlington, Massachusetts, has a medical collar that can measure a dog’s vital signs and other information to look for signs of pain. Irregularities trigger a notice to by phone, text or email.

Voyce, created by I4C Innovations and based in Chantilly, Virginia, has a consumer version that tracks similar information. It also has a Voyce Pro that is available to veterinarians.

The collars are available online starting at $150. There’s also a monthly charge of about $10 to $15.
