How Big Should a Dog House Opening Be? (Solved & Explained!)

To determine the proper size for a dog house opening, measure from your dogs feet up to their shoulders. Dogs don’t mind ducking to enter their dog house, so a door which is as tall as their shoulders will be a perfect fit for coming in and out as they like.

For the remainder of this article, we’re going to answer the most popular questions on the subject of dog houses and especially on the dimensions involved when building a DIY dog house. Read on to find the information that you need for building your own DIY dog house!

How wide should 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 their feet to the top of their 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%.

What angle should dog house roof be?

If you are building a DIY dog house then the ideal angle for the roof is going to be 45 degrees. This will allow you to apply tar paper and to shingle the roof like you would for a human dwelling and the rain should bounce and roll off of it quite nicely.

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 them. The width should be the length of your dog plus 10% as well in order 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 do I get my dog to use his dog house?

 When you get or build a new dog house, you should load it up with some comfortable bedding, such as blankets, straw, or wood shavings (pine or cedar) and put some toys and treats inside. Show it to your dog and toss a treat inside in front of them and let them investigate it.

While they might not stay inside right away, a little unsupervised time in the yard is very likely to change that when your dog feels like taking a little nap somewhere in the shade.

How big of a house does a German shepherd need?

A German Shepherd needs a house that is 25% taller than they are and it should also be 25% longer than their body length. The width should be their body length plus about 10%, as well.

If you have a purebred, then get a house that fits these specifications for a fully grown Shepherd so that your dog can grow into it.

How do you insulate a dog house?

You can insulate the inside of a dog house with fiberglass insulation, much like you would a human house, or you can use Styrofoam. Styrofoam is an inexpensive, but effective option and it’s quite easy to work with.

Just cut the foam up into panels for the 4 walls and the roof, affix these into place, and your dog house is officially insulated!

Does a dog need a house?

For an inside dog, a dog house is more of a luxury than a necessity, but for an outside dog it is absolutely vital. The dog house gives your dog protection from the weather and from the heat and cold, providing them with a safe shelter and a place to sleep.

All that you need to add inside is bedding and a few favorite toys and you’ve got the perfect dog house.

Does a dog house keep a dog warm?

On average, it’s going to be about 10 degrees warmer inside the dog house than outside of it. You can greatly increase this number by using better insulation, which can sometimes result in a doghouse that is 25 degrees warmer or more!

Additionally, you can add extra bedding to fill up the empty space, and this will also improve the interior temperature, as it will take less energy for your dog to heat up the inside with their natural body heat.

Should you paint the inside of a dog house?

No, there is no need to paint the inside of a dog house and doing so might actually deter your dog from using it. For one thing, most paints have VOCs, also known as ‘volatile organic compounds’, which produce fumes that are toxic to humans and dogs alike.

Even with a non-toxic paint, there will be some smell to it, and your dog might well want to avoid this. It’s better to simply keep the paint on the outside of the house.

What materials do you need for a dog house?

If you are building a doghouse, the easiest wood combinations will be plywood and something which is decay resistant, such as cedar or redwood. You’ll also want to have some tar paper and roofing shingles, as well as some Styrofoam to shape for insulation inside.

Finally, you can use rubber mats on the floor if you’d like something a little easier to clean.
