Leaving a dog in a car with the AC on can be safer than leaving them in a hot car without any cooling, but it still carries some risks and is generally not recommended. Here's why:
Temperature fluctuations: Even with the AC on, the temperature inside a car can change quickly, especially if the car is turned off or the AC malfunctions. Dogs are sensitive to temperature changes, and the car could become dangerously hot if the AC stops working.
AC malfunctions: Air conditioning systems can fail unexpectedly, and if you are not there to notice the issue, your dog could be left in a hot car.
Power outage: If there's a power outage or the car runs out of fuel, the AC will stop working, potentially putting your dog at risk.
Inadequate ventilation: Even with the AC on, cars are not as well-ventilated as the outdoors, and the air inside can become stale or lack oxygen.
Noise and stress: The sounds and vibrations of a running vehicle might be stressful for some dogs and could lead to anxiety.
Unforeseen circumstances: You might intend to leave your dog in the car for a short time, but situations can change, and you may end up being delayed.
As a general rule, it's best not to leave your dog unattended in a car, regardless of whether the AC is on or not. If you need to travel with your dog, try to take them with you whenever you leave the car. If that's not possible, consider alternatives, such as leaving your dog at home, using pet-friendly establishments, or traveling with a friend or family member who can look after your dog while you're away. The safety and well-being of your furry friend should always be a top priority.
