Can Snakes Get in Doggie Doors? Risk and Solutions

The concept of snakes slithering through doggie doors might sound like a scene from a horror movie, but is it really something pet owners should be concerned about? Many dog owners worry about the safety of their furry friends and the potential risks they might face, including encounters with wildlife. 

In this article, we’ll delve into the intriguing question: Can snakes get in doggie doors? We’ll explore the biology of snakes, the design of doggie doors, and provide practical solutions to help keep your pets and home safe.

The Biology of Snakes

To determine whether snakes can access your home through a doggie door, it’s essential to understand the biology of these fascinating creatures. Snakes come in various sizes and species, and their physical abilities can vary greatly. 

Most snakes are incredibly flexible and can squeeze through surprisingly small openings. Their bodies are composed of numerous vertebrae that allow them to move in a wide range of directions.

Snakes are also skilled climbers, which means they can ascend walls, trees, and even the exterior of houses. Some species are excellent burrowers, capable of squeezing through gaps beneath doors or other openings. 

To add to their versatility, snakes possess specialized scales that allow them to reduce their body size when necessary, enabling them to fit through tight spaces.

Doggie Doors: A Gateway for Snakes?

Doggie doors are designed to provide pets with easy access to the outdoors, offering them the freedom to come and go as they please. However, these openings might inadvertently invite unwanted guests, including snakes.

Snakes can potentially exploit doggie doors, especially if the doors are large enough to accommodate their size. A common concern is that a snake, attracted by the scent of food or warmth, might slither through a doggie door and find its way into your home. 

While the likelihood of this happening varies depending on factors such as the size of the snake and the dimensions of the door, it’s not entirely impossible.

Factors to Consider

Several factors determine whether a snake can enter through a doggie door:

Size of the Snake: Smaller snake species are more likely to fit through a doggie door, especially if the door is designed for larger dog breeds. Snakes with a smaller girth can navigate tighter spaces.

Size of the Door: The dimensions of the doggie door play a crucial role. A small door designed for toy breeds might not allow most snakes to enter, but larger doors for bigger dogs could potentially accommodate certain snake species.

Location of the Door: If the doggie door is situated close to vegetation, a snake might be more inclined to explore the area and attempt entry.

Weather Conditions: Snakes are ectothermic, meaning their body temperature is regulated by their environment. On cooler days, a snake might seek warmer spaces, which could lead them to investigate potential openings, like a doggie door.

Mitigating the Risk

The safety of your pets and home is paramount, and there are steps you can take to minimize the chances of snakes entering through a doggie door:

Choose the Right Size: If you have a smaller dog, opt for a doggie door that is appropriately sized for your pet. This reduces the likelihood of a snake squeezing through.

Install Barriers: Consider installing barriers, such as mesh screens or flaps, on both sides of the doggie door. These barriers can prevent snakes and other wildlife from entering while still allowing your pet to pass through.

Regular Inspections: Regularly inspect the area around the doggie door, both inside and outside your home. Trim back any vegetation or debris that might attract snakes.

Seal Other Entry Points: Snakes can find their way through other openings, such as gaps under doors or cracks in walls. Seal these openings to further discourage snake intrusion.

Secure at Night: Snakes are more active during the day. To further reduce the risk, consider securing the doggie door at night when your pet is indoors.


While the thought of snakes using doggie doors as entry points might be unsettling, the risk can be managed with careful consideration and proactive measures. Understanding the biology of snakes and the capabilities of different species is key to assessing the potential danger. 

By selecting the right doggie door size, installing barriers, and regularly inspecting your home’s surroundings, you can help keep your pets safe and prevent unwelcome wildlife encounters. Remember, a well-informed pet owner is a pet’s best line of defense.
