What is a Smart Pet Door?

smart pet doors dogs and catsIf you’re constantly playing doorman for your pets, a smart dog door can be a real time saver. While a traditional dog or cat door typically just provides a flap and insert for your door, you can fine-tune a smart dog door for optimal performance according to your specific needs.

But what are smart dog and cat doors exactly?

In general, a smart dog door is a pet flap that incorporates electronics and other innovations. It is frequently used in conjunction with a microchip or pet collar to control which pets are allowed to enter and exit your home. They often have locking mechanisms incorporated, making them ideal for keeping your kids from making an undesirable exit and your animals safe.

Perhaps this is why a recent study by Future Market Insights (FMI) predicts that the global pet door market will grow at an impressive 6.6 compound annual growth rate (CAGR) between now and 2031.

These doors frequently require a key that detects when your pet is approaching them. This key could be something as simple as an RFID key that attaches to your pet’s collar or as complex as having the ability to recognize your pet’s individual microchip, producing a collar-free experience. These doors are highly suitable for several breeds and sizes of dog, whether you have a golden-brown chihuahua or a white german shepherd.

  • You want to be able to control when your pets can go outside, but you are frequently away from home.
  • You have a curious child small enough to fit through a standard “dumb” pet door.

Are Smart Pet Doors Safe?

No pet door is specifically designed to keep a child safe, but smart doors do offer a huge benefit over their non-electronic counterparts due to additional features such as RFID or microchip sensors and door open/close timers. Another benefit when deciding on a smart pet door for small dogs and cats is that the average opening is only 6” x 7”.

However, no pet door is truly child-proof, so it’s important to remember that the best protection for a young escape artist is your own vigilance and a child-proofed yard. Additionally, installing a door sensor can provide added peace of mind.
