The \u003cstrong\u003eJonart Extension Pen - Rail Sides\u003c\/strong\u003e is the \u003cstrong\u003ewhelping box extension pen\u003c\/strong\u003e built for exactly that stage. This rail-sided \u003cstrong\u003epuppy play pen extension\u003c\/strong\u003e attaches to your \u003ca href=\"\/products\/jonart-whelping-box-with-floor\"\u003eJonart Whelping Box - With Floor\u003c\/a\u003e and adds a full second enclosure of additional space for play, training and growth, so growing puppies get a safe \u003cstrong\u003epuppy play area\u003c\/strong\u003e of their own while your dam gets her nursery back. As Lakeside puts it, this is an extension pen with rail sides to add additional space for play, training and growth — and breeders who whelp in a Jonart know there is no substitute for a pen that fits the box perfectly, panel for panel, bolt for bolt. If you have been searching for a \u003cstrong\u003eJonart extension pen\u003c\/strong\u003e, a \u003cstrong\u003eweaning pen for puppies\u003c\/strong\u003e or a \u003cstrong\u003ebreeder puppy pen\u003c\/strong\u003e that works as a true system instead of a workaround, this is it.\u003c\/p\u003e\n\u003ch2\u003eThree Rail-Side Panels — and No Floor Panels, By Design\u003c\/h2\u003e\n\u003cp\u003eThe \u003cstrong\u003eJonart Extension Pen - Rail Sides\u003c\/strong\u003e is made up of 3 additional panels: (2) side panels and (1) front panel. Extension pens have \u003cstrong\u003eNO floor panels\u003c\/strong\u003e — the pen extends the footprint of your whelping setup and sits on your own flooring, matting or whelping pads, while the Jonart whelping box itself keeps its insulated raised floor for the youngest puppies. The open \u003cstrong\u003erail sides\u003c\/strong\u003e are the point: puppies can see the room, watch their littermates and get comfortable with household sights and sounds, you and the dam can see in at a glance, and air moves freely through the pen. That visibility makes this \u003cstrong\u003epuppy play pen\u003c\/strong\u003e a genuine training space — room for first toys, first litter-box habits, first meals away from the box — and a natural \u003cstrong\u003eweaning pen\u003c\/strong\u003e as puppies transition from the whelping box to the wider world.\u003c\/p\u003e\n\u003ch2\u003eBuilt Like the Jonart Whelping Box It Attaches To\u003c\/h2\u003e\n\u003cp\u003eThis is not a flimsy exercise pen. The \u003cstrong\u003eJonart extension pen\u003c\/strong\u003e is part of the same modular Jonart system as the whelping box: a heavy duty plastic frame and FRP plastic panels held together with carriage bolts, so the pen is rigid, sturdy and strong enough for active litters — and smooth, hard and non-porous, so it wipes clean between litters. Lakeside's Jonart line is built for ultimate structural stability, and the extension pens are the matching modular expansion for that system: replacement panels are shared across Jonart whelping boxes and extension pens, so your setup can be serviced and reconfigured for years. Jonart products are crafted by Lakeside Products in Polk City, Iowa, and this extension pen is backed by a \u003cstrong\u003e1 Year Warranty\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch2\u003eChoose the Extension Pen Size That Matches Your Whelping Box\u003c\/h2\u003e\n\u003cp\u003eExtension pens are sized to match the Jonart Whelping Box - With Floor exactly.
