Frequently Asked Questions:

How do you lock a sliding glass dog door?

Since most patio panels cannot “mate” with the lock of your sliding glass door, they come with a foot lock that clamps over the lip of the sliding door track. For additional security or for monorail tracks, a wooden dowel or Charley Bar is recommended.

Can you put a dog door in a double sliding door?

Yes, but one of the sliders must be made stationary, leaving only one slider operational.

Should I get an aluminum or vinyl dog door for sliding doors?

It’s best to match the material of the pet door with the material of your sliding door, either vinyl or aluminum, for aesthetics and a snug fit.

Which is the best sliding glass door for large dogs?

The Hale Omni Panel Pet Door for Sliding Doors is a top choice for large dogs, accommodating even giant breeds. The next largest pet flaps can be found in the Endura Flap product line. 

What if I have a monorail track?

Most pet door panels are designed for u-shaped tracks, so you may run into a few issues. For monorail tracks, some panel pet doors, like those made by Dragon Pet Door and the Whiskers & Windows, can use a monorail adapter. Otherwise, you may need more permanent solutions, like those made by Pet Door Guys or Utah Pet Access. 


When choosing a pet door for sliding glass doors, it's essential to consider factors like the weather conditions, door material, size of the pet, and installation ease. The doors mentioned above offer a comprehensive range for every need. The right door will provide both you and your pet with the freedom, safety, and comfort you deserve.
