The Collar has temperature sensor sends alerts to the phone if the you’ve forgotten your pet in hot car. The accelerometer and altimeter can be used to warn you if your usually perky pet is unusually sedated, a sign of potential health problems. You can also pacify your pet with an ultrasonic buzzer to prevent unnecessary dog fights. Notifications about your pet's health and reminders for vaccinations are sent to your phone and shown on the LED display on the collar.
