If you’re a dog owner, you know how important it is to provide your pet with a comfortable and safe place to rest. One of the most important factors to consider when building or buying a dog house is the size of the door opening. The size of the opening can affect your dog’s comfort, safety, and overall well-being.
So, how big should a dog house opening be? The answer depends on several factors, including your dog’s size, breed, and age. Generally, the opening should be large enough for your dog to enter and exit comfortably, but not so large that it lets in too much cold air or rain.
The size of the door opening should be based on your dog’s size. A small dog needs a 6 by 7-inch door, a medium-sized dog an 8 by 15-inch door, a large dog a 10 by 19-inch door, and an extra-large dog will need a 12 by 23-inch door. However, it’s important to note that these are just general guidelines and you should always consider your individual dog’s needs before making a decision.

Why the Size of a Dog House Opening Matters
The size of the dog house opening matters because it affects your dog’s comfort, safety, and health. If the opening is too small, your dog may not be able to enter or exit the house easily. On the other hand, if the opening is too large, your dog may feel exposed to the elements and predators.
A dog house opening should be 25% taller and 25% longer than your dog. The width should be your dog’s length plus 10%. This ensures that your dog has enough space to move around and feel comfortable, but not so much space that they have to expend extra energy to heat the extra space in the winter.
The height of the opening is also important. According to Hayneedle, the height of the opening should be about 80% of your dog’s shoulder height. This ensures that your dog can easily enter and exit the house without having to crouch or jump.
Another factor to consider is the location of the opening. The opening should be located on the side of the house that is sheltered from the wind and rain. This will keep your dog dry and warm during inclement weather. Additionally, the opening should not face directly into the sun, as this can cause the house to become too hot for your dog.
Factors to Consider When Choosing the Right Size for Your Dog House Opening
Dog Breed
The size of your dog’s breed is an important factor to consider when choosing the right size for your dog’s house opening. Smaller breeds like Chihuahuas and Yorkshire Terriers require smaller openings, while larger breeds like Great Danes and Saint Bernards need larger openings. It’s important to measure your dog’s height and width to ensure that the opening is not too small or too large.

Dog Size
The size of your dog also plays a significant role in determining the size of the dog house opening. As a general rule, the opening should be about 25% taller and 25% wider than your dog. This allows your dog to enter and exit the dog house comfortably. However, it’s important to note that the opening should not be too big, as it can cause heat loss in the winter and make the dog house less energy-efficient.
Climate
The climate in which you live is another important factor to consider when choosing the right size for your dog house opening. In colder climates, a smaller opening is recommended to keep the warmth inside the dog house. In warmer climates, a larger opening is recommended to allow for proper ventilation and airflow. It’s important to find a balance between the size of the opening and the climate to ensure your dog is comfortable and safe.

How to Measure Your Dog for the Perfect House Opening Size
When it comes to determining the size of your dog’s house opening, it’s essential to measure your dog accurately. An appropriately sized dog house opening can provide your pet with comfort and security, making it a vital factor to consider. Here’s how to measure your dog for the perfect house opening size:
First, measure your dog’s height from the ground to the top of its shoulder blades. This measurement will help determine the height of the dog house opening.
Next, measure the width of your dog’s shoulders. This measurement will help determine the width of the dog house opening.
Finally, consider your dog’s weight and breed. A small dog needs a 6 by 7-inch door, a medium-sized dog an 8 by 15-inch door, a large dog a 10 by 19-inch door, and an extra-large dog will need a 12 by 23-inch door.
It’s important to note that the size of the dog house opening should not be too big or too small. The opening should be big enough for your dog to comfortably enter and exit the house but small enough to keep them warm during the colder months.
Remember to measure your dog accurately to ensure that they have the perfect house opening size. A well-sized dog house opening can provide your pet with a comfortable and secure space to call their own.
Common Dog House Opening Sizes
If you’re wondering what size opening your dog house should have, it’s important to consider your dog’s size and breed. Here are some common dog house opening sizes:
Dog Size | Opening Size |
---|---|
Small | 6 by 7 inches |
Medium | 8 by 15 inches |

It’s important to note that these are just general guidelines, and you should always measure your dog to ensure the best fit. Additionally, you should consider the climate in your area and make sure that the opening is not too large or small, as this can affect your dog’s comfort and safety.
Remember, a dog house with the right opening size can provide your pet with a cozy and safe place to rest and relax.
Conclusion
Choosing the right size for your dog’s house opening is crucial for their comfort and safety. A door that is too small can make it difficult for your dog to get in and out, while a door that is too big can make the house drafty and uncomfortable.
Remember to measure your dog’s height and length, and use the recommended formulas to determine the appropriate door size. Additionally, consider the climate in your area and the materials of the house to ensure that your dog stays warm and dry.
By following these guidelines, you can provide your pet with a cozy and comfortable home that they will love.

FAQ
How wide should the dog house door be?
That depends on the dog, but if we go by kennel door sizes, a small dog needs a 6 by 7-inch door, a medium sized dog an 8 by 15-inch door, a large dog a 10 by 19-inch door, and an extra-large dog will need a 12 by 23-inch door.
These numbers should give you a good approximation when you hunting for a new dog house.
What dimensions should a dog house be?
To determine the optimal dog house size, measure your dog from its feet to the top of its head, and the height of the house should be 25% higher than this.
Next, measure from the tip of the nose to the tip of the tail and the length of the house should be this measurement plus 25%, while the width will be this measurement plus 10%.
Should a dog house have windows?
Windows are a great addition to any dog house. They will allow your dog to take advantage of cross breezes in the summer and dogs also love being able to sit inside their house and peep out whenever they like.
Just be sure to add a little extra bedding when the winter comes, to help compensate for the heat loss that comes with windows.
How much space does a dog need in a house?
As a general rule, a dog house should be 25% taller than your dog, as well as 25% longer than theirs. The width should be the length of your dog plus 10% as well to ensure that your dog is comfortable.
You don’t need anything bigger than this, as your dog will only end up expending extra calories heating the extra space in winter.
How big of a house does a German shepherd need?
