Easy to Install Dog Doors for Big Dogs

  • Heavy Duty Dog Door for Large Dogs with Hardware Included: Only 2 Screws Needed
  • Rough Opening required: 16-1/2” x 25-1/2” (Note: if you're using our Trim Kit, you must follow that recommended opening size of 17-1/4" x 26-1/4")

Where to create the Opening:

  • Measure the distance from the ground to the lowest part of the dog's chest
  • Subtract 2"
  • This is where the opening will start and go up 25-1/2" from that spot OR determine the height off the ground given a 25-1/2" opening where your dog will not have to duck down or jump over to use the door.

If you have puppies in a run, your dog is older, or needs easier access, try out the Easy Big Dog Door instead.
