The Ultimate Guide to Choosing the Right Door for Your Dog

The notion of installing a dog door often raises concerns about security and unwanted animal intrusions. However, when chosen wisely, your dog’s door can offer unparalleled freedom for your furry companion. A myriad of options exists for different types of doors, including sliding glass, screen, or patio doors. To optimize the benefits, pet owners need to weigh several considerations.

Measure First, Install Later

Often overlooked, measuring your dog’s height and weight is the foundational step.

Height: Choose a door that stands at least two inches taller than your dog’s shoulder height. Dogs typically lower their heads to push open the flap.

Width: Consider future weight gain and opt for a door that’s about two inches wider than your dog’s widest body part.

For households with multiple dogs, ensure the door accommodates both the smallest and largest pets.

Factors Influencing the Choice

The ideal dog door depends on a variety of aspects, including installation location, proximity to electrical and plumbing systems, features, budget, and energy efficiency. Advanced options like microchip or electronic collar key-synced doors and DIY installations are also available. A thorough examination of these factors is essential.

Additional Elements to Consider

Children: Safety concerns arise when young children access dog doors, leading many pet owners to opt for electronically locking doors to mitigate risks.

Wildlife Intrusions: In areas prone to wildlife, selecting doors with automatic locking mechanisms aligned with your pet can deter intruders.

Training Needs: For puppies or dogs in training, doors with robust latching systems offer control over ingress and egress.

Energy Efficiency: While the initial investment and associated energy costs can be substantial, energy-efficient doors can mitigate long-term expenses.

Outdoor Environment: The safety of the external environment is pivotal. Ensure your backyard is secure and escape-proof.

The Path to Adaptation

Training is pivotal; just because a dog knows how to use the main door doesn’t mean a dog door will be instantly intuitive. Pet owners should acclimate their dogs to this new mode of entry and exit well ahead of installation.


Selecting a dog door transcends mere convenience; it’s about aligning the needs and safety of your canine companion with the household’s overall dynamics. From the dog’s size and the household’s human occupants to the surrounding environment and potential wildlife intruders, every facet plays a crucial role. A well-chosen dog door not only ensures your pet’s freedom of movement but also aligns with the safety, security, and energy efficiency of your home.
