It seems useful and feels accomplished to see your dog using a personal door. However, you'll go through a lot from assessment to installation and finishing before you can make it happen. Remember to seek help from a professional if you're uncertain about this DIY project, as some of the steps include altering your house's wall.

1. Assess the Area

First of all, familiarize yourself with the interior and exterior of the wall. You should not drill holes through any weak, damaged part of the wall. Avoid cutting near the wiring and waterpipes. So, choose the safest spot in making a dog door.

Considering that the dog door is on a lower level of the wall, ensure that the area is not prone to flooding. The rainwater could pour into your house through the dog door.

Check also if the space in front of the dog door is open. You don't want your dog to struggle to go out if there's another obstacle in front of the door.

2. Prepare the Tools

It's important to know the tools. You may need to buy those tools that are not available in most homes. Aside from the door you'll install, see the list of tools below:

  • Drill
  • Hammer and nails
  • Safety gloves
  • Tape measure
  • Pencil
  • Level
  • Wall cutter
  • Screwdriver
  • Silicon caulk

3. Find the Best Door to Use

Dog doors differ in size, style, and surface compatibility. Some of them are made for glass doors or other door surfaces. That's why we're sharing with you some door types you can use in a cinder block wall. Refer to the list below.

Flap Door

A flap door has a rod on the top portion to allow a swinging motion when your dog walks past it. You can choose either a one-way or two-way flap door depending on your preference.

  • A one-way flap door lets your dog exit or enter the house, restricting your dog to go back to the opposite direction.
  • On the other hand, a two-way flap door allows your dog to go in two directions.

Most flap doors have a lock. This is to prevent other dogs from entering, especially while sleeping or when you're away. There are also options on the frame such as wood and aluminum, that are both compatible with a cinder block wall. So, consider the specifications of a flap door before having one.

Electronic Door

An electronic dog door is usually activated by a detection device. This will automatically open once it detects a programmable collar on your dog. That's why, there's no other dog that can pass through the door.

Electronic doors are expensive among other door types. However, you can also install it on a wall. Just check the instruction of use to see if it will fit your needs.

See this (various sizes) electronic dog door at Amazon.

Also, electronic dog doors require maintenance. You should check the wires or batteries to let the door function continuously. It's best to ask the manufacturer to assess your house before installing an electronic door. It's crucial to keep the area safe, especially when wires are included.

Tunnel Door

Tunnel doors are similar to flap doors, except they have an extension protruding a few inches away. Its purpose doesn't differ that much, but it can add appeal to your home and give more space for the dog. You can even decorate the tunnel to personalize its look.

However, you need to consider the protrusion distance when installing the tunnel door. Make sure it will not be an obstruction to your house, deck, or walkway. Check also the size, as tunnel door is not made for all dog sizes.

4. Measure and Cut the Wall

It's ideal to bring your dog with you when buying a door to test the door's height. The door should be an inch higher from the dog's shoulder, and two inches wider on the sides.

So, measure the door and trace it on the wall with a pencil. Align the door on the ground with a level. Allow a step-over at least one-third of the dog's height. This is to keep the dog comfortable when stepping in and out.

See this tape measure on Amazon.

After tracing the door, drill into the corners. From there, start cutting the wall with a grinder. Remember to wear your safety gloves. Use a hammer to break the wall faster. Continue until you outlined the hollow.

5. Fit the Door into the Hole

Mount the door frame into the hollow. Screw the corners and edges. If the frame is made of wood or aluminum, you can use a hammer and nails to mount the frame. You may also refer to product instructions of use for accurate installation.

6. Trim the Edges and Seal the Gaps

Use a silicon caulk to seal the gaps between the frame and the wall. It also helps stabilize the frame to prevent unnecessary movements.

How to Install Additional Lock in a Dog Door

You can install another lock aside from the lock that's included in the dog door. An easy option is a hasp latch that has a plate for screwing. Latches may differ in design. Just make sure the hinge will match the size of the door.

See this hasp latch on Amazon.

To do so, you can follow the steps below.

  1. Make sure you're inside the house when installing the hasp latch.
  2. Use a pencil to mark the screwing holes on the door frame.
  3. Drill holes on the marked spots.
  4. Screw the plate tightly in place. Check also the product's intended use guide.
  5. Test the door and the lock.

Why Your Dog Doesn't Use the Dog Door?

Your dog may not like the door on the first day you installed it. It's important to give the dog time to recognize and understand the purpose of the door. See below for some reasons why your dog doesn't use the door, and what to do about it.

The Dog Is Confused

Not all dogs can understand instructions when you tell them to go through the door. They might be confused about what you're trying to do, or why they need to use the door. Try giving your dog a treat going outside. Do this until your dog gets comfortable from going in and out of the door.

You can also roll a toy ball through the door. The dog's instinct is to follow the ball and give it back to you. This will make the dog memorize the door's purpose.

The Dog Outsized the Door

It's possible that your dog is getting bigger either by fattening or natural aging. If it's the case, you need to replace the door with a bigger size as well. However, installing a new door can be costly.
