It is important to keep dogs — especially young puppies — supervised or safely contained so they do not injure themselves or destroy your home. While outdoor accommodations require more security, you can build a simple DIY PVC dog kennel, suitable for confining dogs while they are indoors. Building your own PVC dog kennel will allow you to save money and customize the kennel to suit the space available.

Tip
Half-inch-diameter PVC works well for small puppies, but ¾-inch pipe works better for larger puppies and small adult dogs. If you opt to use ¾-inch pipe, be sure to purchase ¾-inch connectors.
Step 1: Measure and cut PVC pipe
Measure a dozen 4-foot long sections and a dozen 6-foot long sections of PVC using the tape measure. Mark the lengths on each pipe with the pen. Cut each pipe with the hacksaw to produce 24 individual pipe segments that will line your DIY PVC dog house.
Step 2: Place connectors to pipes
Identify two 4-foot long sections and two 6-foot long sections as the top railing. Place a three-way coupler on each end of these four pipes. The remaining pipes will form the middle and bottom rows, so attach a four-way connector to both ends of each pipe.
Step 3: Measure and mark segments
Measure and mark 48 segments of PVC pipe 1 7/8-inch long with the tape measure and pen. Cut along each marked line with the hacksaw.
Step 4: Lay pipes into a rectangle

Insert a 1 7/8-inch-long segment in all three open slots on each end of two different 4-foot pipes. Do the same thing for two 6-foot pipes. Lay each of these pipes on the ground so they create a rectangle. Designate one side of each pipe as the top and the opposite side as the bottom. Place an end cap over the 1 7/8-inch segments on the bottom of each pipe. These capped segments will serve as the feet for the PVC dog kennel.
Step 5: Connect long and short sides
Connect the long sides to the short sides by attaching a 90-degree elbow to the 1 7/8-inch segment extending from the end of each short pipe. Insert the 1 7/8-inch segment on the long pipes into the open end of the 90-degree elbows. You should now have a completed rectangle, with two capped feet on each side. Additionally, each side should have two 1 7/8-inch-long segments sticking straight up.
Step 6: Repeat the process
Repeat this process four more times, but do not insert the 1 7/8-inch segments into the bottom side of each segment, as the row below it already will have one. Finally, create the sixth and final row, but use three-way connectors in place of four-way connectors.
Step 7: Test PVC dog kennel safely

Test the stability of your PVC dog kennel by shaking sections of it and seeing if it moves. If the DIY PVC dog house rocks, shakes, or collapses, it needs some adjustments. Even after your dog kennel is finished, you'll need to check it regularly to make sure it is still safe for your canine companion. Check for any wear and tear, like splintered pipes, cracked PVC, or any sharp edges that could hurt your four-legged friend. As long as you take care of your PVC dog kennel, it should save you money and last for years to come.
