【Designed for Indoor Use】When our indoor user base exceeded 30%, we realized that beyond the Rollick playpen, which can be adapted for indoor use with accessories, we should offer a more straightforward solution: a playpen designed specifically for indoor environments. Thus we developed the Homeplus dog playpen. 【Threshold-Free Design is Convenient for Dogs to Enter and Exit】Puppies with weak jumping ability, small dogs, or old dogs with limited mobility can pass easily. The automatic gravity lock design will ensure that you can open and close the door smoothly and reduce the chance of your dog unlocking it by itself. 【Muffler Tubes Create a Quiet, Fenced Space】The Muffler Tube installed on the rings can minimize any noise caused by the rattling of the rods or panels, so that you can play with your dog in a quiet environment. At the same time, it reduces the friction of the rods during use and prevents wear on the metal coating. The hook design ensures that this little accessory won’t fall off, so you don’t have to worry about your dog eating it by mistake. 【Silicone Pads Enhance the Stability of the Playpen】Anti-slip silicone pads installed on the stakes and the panel bottoms provide friction to reduce the possibility of the fence being pushed down or dismantled by your dogs. These pads also prevent the stakes from scratching your floors. Note: If you want to set up a pet's play area outdoors, we recommend our Rollick Playpen. The bottom of the stakes is designed with a conical shape, which makes them easier to insert into the ground.
