1. Easy DIY Outdoor Dog House Plans
A good dog house is simple. Four walls, a roof and a raised floor are all it takes, as long as the size is right.
Measure your dog first. The house should be about 25 percent longer than your dog from nose to tail base, and about 25 percent taller than your dog standing. The door should be a little lower than your dog’s shoulders.
⏱ 6 hours💲 Medium🛠 Medium
Materials Needed
- Exterior plywood sheets, 3/4 inch
- Cedar fence boards, 1 by 4 inch
- Asphalt roll roofing
- A saw, a drill, exterior screws and a tape measure
How to Make It
- Measure your dog’s length, height and shoulder height, and decide the size of the floor, walls and door.
- Cut the floor from plywood and screw it to four short pieces of 2 by 4 so it sits 4 inches off the ground.
- Build four walls from cedar boards on a frame, with a door cut a little lower than your dog’s shoulders.
- Screw the walls to the floor and add a sloped roof with a small overhang.
- Cover the roof with roll roofing and sand every edge smooth.
Tip: Check that your dog can stand, turn around and lie down inside. Leave a small vent gap under the roof and never use treated wood inside.
2. Large Insulated Outdoor Dog House for Large Dogs
Big dogs need big houses. A large insulated house keeps out wind and holds the dog’s own warmth in.
Build a double wall, with foam board between two layers of plywood. Cover the foam fully, so your dog can’t chew it. Raise the floor, add straw for bedding and use a flap or a short tunnel at the door.
⏱ 8 hours💲 Medium🛠 Hard
Materials Needed
- Rigid foam board insulation, 1 inch
- Exterior plywood, 1/2 inch
- Straw bedding for dog houses
- A saw, a drill, exterior screws and a tape measure
How to Make It
- Measure your large dog and add 25 percent to the length and height to find the size of the house.
- Build the floor frame on legs, and cut foam board to fit between two layers of plywood.
- Build the walls as a double layer, with the foam sealed between plywood so it can’t be chewed.
- Add a slanted roof with an overhang, and cover it with roofing or metal sheets.
- Add a door at shoulder height, then fill the house with a thick layer of straw.
Tip: Never use heat lamps or space heaters in a dog house, as they are a fire risk. Use straw, not blankets, which hold moisture and get cold.
3. Pallet Dog House
Pallets are cheap and sturdy. A few of them make a nice dog house with a rustic look.
Only use pallets stamped HT, which means heat treated. Avoid MB, which means methyl bromide. Take the boards apart carefully, sand them smooth and check for nails and splinters.
You’ll need: pallet wood pry bar
Best for: recycled wood and low budgets
4. Cheap Scrap Wood Dog House
Leftover wood is free, and it works. Piece boards together for walls, and use a sheet of plywood for the roof.
Keep gaps tight so wind and rain can’t get in, and cover the roof with a waterproof layer. Large dogs can still be cheap if you build smart and use scraps for the framing.
You’ll need: exterior wood screws assortment and exterior wood glue
Best for: free wood and tight budgets
5. Door Flap for a Dog House
A door flap keeps wind, rain and snow out, and it keeps the warmth in. It’s the easiest upgrade for any dog house. See also these dog door ideas.
Use a heavy flexible vinyl or rubber flap, and cut it a little larger than the doorway. Fix it along the top edge with a wooden strip, so it swings freely both ways. Teach your dog slowly by holding the flap open at first.
⏱ 30 minutes💲 Low🛠 Easy
Materials Needed
- Dog door flap, clear vinyl
- Stainless steel screws, small
- A screwdriver, a drill, scissors and a strip of wood
How to Make It
- Measure the doorway and cut the flap a little wider and taller than the opening.
- Drill holes along the top edge of the flap, and mark matching holes on a strip of wood.
- Screw the strip and flap to the top inside edge of the doorway.
- Check that the flap swings freely both ways and doesn’t catch.
- Hold the flap open and let your dog walk through, with treats, until it learns.
Tip: Make sure the flap is soft and light so it never pinches your dog. Remove it if your dog is scared and wait a few days.
6. Cardboard Box Dog House
A cardboard house is a quick, free fix for a small dog or a puppy. It’s also a nice test before you build one in wood.
Pick a big, double wall box and tape the seams. Cut a door with smooth edges and add a soft blanket. Keep it indoors and dry. When it gets chewed or damp, replace it.
You’ll need: heavy duty packing tape and large double wall boxes
Best for: puppies and temporary spots
7. Indoor Dog House for Living Rooms
An indoor dog house is a cozy den, and it can look like real furniture. Dogs love a small, safe corner. For more cozy ideas, check these DIY dog bed ideas.
Build it with smooth edges and a flat top, so it can double as a side table. Make the door arched and big enough for easy entry. Use a washable cushion inside.
You’ll need: washable dog cushion
Best for: living rooms and small homes
8. Porch Dog House
A porch is a good spot. The roof gives shade and shelter, and your dog can watch the world go by.
Place the house against the wall, away from the door swing. Raise it a little on feet, and put a non slip mat under it. Don’t leave your dog out in extreme heat or cold.
You’ll need: outdoor non slip mat
Best for: covered porches and mild weather
9. Winter Warmth Tips for a Dog House
Insulation holds your dog’s own warmth in. You don’t need heaters, you need smart building.
Use straw, since it stays dry and warm. Keep the door small and face it away from wind. Add a flap at the door. On very cold nights, bring your dog indoors, because a dog house is never enough in extreme cold.
You’ll need: thermometer for dog house
Best for: cold nights and mild winters
10. Cute Dog House Ideas
A dog house can be cute too. Add a tiny window, a flower box or some trim, and it becomes a little garden cottage.
Keep decorations on the outside, and keep the inside simple and safe. Use pet safe paint and let it dry fully before your dog goes in. Don’t add small parts that could be chewed.
You’ll need: pet safe outdoor paint
Best for: pretty gardens and cute style
11. Raised Floor Dog House With Legs
A raised floor keeps the house dry, and it keeps the cold from creeping up from the ground.
Lift the floor 3 to 4 inches off the ground with solid legs or blocks. Use a small ramp or step at the door, and seal the floor edges so water can’t soak in.
You’ll need: rubber feet for outdoor furniture
Best for: wet yards and damp ground
12. Easy Small Dog House for Small Dogs
Small dogs need small houses. A tight space holds their warmth, and a cozy shape makes them feel safe.
Keep the house about 25 percent longer than your dog. A smaller space warms up faster. Use a light plywood and a bit of insulation, and keep the door low and wide.
You’ll need: small dog cushion for house
Best for: small dogs and puppies
13. Sloped Roof Dog House With Overhang for Rain
A good roof is half the house. A slope sheds rain, and a long overhang keeps the door dry.
Make the roof slope to the back so water drains away from the door. Add roofing felt or metal sheet on top. Hinge the roof if you like, so you can lift it for cleaning.
You’ll need: roofing felt rolls
Best for: rainy weather and dry doors
14. Dog House With a Windbreak Entry
A short tunnel or windbreak at the door stops the wind from rushing straight in.
Build a small box at the front, and turn the opening to the side. Your dog turns once to enter, and the warm air stays inside. Face the opening away from the wind.
You’ll need: heavy plastic strip curtain
Best for: windy yards and cold weather
15. Safe Paint and Decor for a Dog House
A fresh coat of paint protects the wood and makes the house look new. Just pick the right paint.
Use non toxic, pet safe outdoor paint. Paint the outside only, and let it dry for several days before your dog uses it. Keep the inside bare and smooth.
You’ll need: outdoor wood stain pet safe
Best for: fresh looks and wood protection
