Type of Dog Door

Coming in a few different styles, each dog door is best suited for various situations, dogs and owners. The most common ones include:

Door-Mounted Dog Doors:

This is the most popular pet door which is designed to be mounted directly in the lower portion of standard doors. It can be said that when people think about the phrase “pet door”, they will imagine this kind of door. Each model works best with different types of pet doors. Therefore, be sure to review and consult the manufacturer’s recommendations and instructions before making your decision.

Wall-Mounted Dog Doors:

Similar to a door-mounted dog door, a wall-mounted door is designed to be installed into a certain hole which is cut into the wall, rather than the door. Typically, they are deeper/ thicker than a door-mounted one, or a relatively thin door. However, the installation process is more complicated, and you may need a mechanic to do this as this kind of door requires requisite skills as well as tools to install it into the wall.

Electronic Dog Doors:

The electronic door varies widely. While some can open and close automatically, others are just passive, and designed to restrict the pet’s access through programmed options, or they are triggered by a RFID chip which is attached to your pet’s collar. The electronic door is typically designed to be installed in a standard home door, instead of glass doors or walls.

Sliding Door Dog Doors:

There are doggie doors which are designed to well-fit into the gap created by an opened sliding glass door. It’s quite easy to install; however, they seem to be more expensive than other door-mounted doors because they require a full-length section of a glass door. Another limit is that they will make your sliding door become inoperable for humans to use.
