NBC - This week Tesla cars will receive an update, which includes a "dog mode."
A fan tweeted at Elon Musk in October asking for a dog mode which keeps the ac on and plays music.
The mode will also include a message on the car's display screen saying "I'm fine my owner will be right back."
Musk said on Thursday that the update will be rolling out this week along with a new security feature "sentry mode," which blasts classical music if the car detects it's being broken into.
Tesla updates are carried out remotely, as they are done via the cars' software.
The American Veterinary Medical Association says hundreds of pets die every year from heat exhaustion because they are left in parked vehicles.
It said the temperature inside a car can rise almost 20 degrees in just 10 minutes.
