From the manufacturer:
GENERATION II MID-SIZE KENNEL
Introducing RuffLand Gen II Performance Kennels! For 2022, we are introducing newly designed Ruff Land Kennels. The fact is that we’ve sold so many kennels in the past few years that our molds are beginning to show wear. So, we took this opportunity, in building all new molds, to make some refinements to our kennels. Most notably, all kennels now include handles that are recessed for stacking and accessorizing. Fit and finish is also much more uniform. And, we will be able to offer a wider variety of accessories many of which will be specifically designed to fit the various size kennels.
When the Medium Kennel is more than you need but the small is not roomy enough; meet the Mid-Size! The newest in our line of kennels comes in response to dog owners and show go-ers requests. The Mid comes standard with a handle and 1" vent holes. Note: It is not stackable or able to couple with smalls or mediums.
THIS IS A NON-RETURNABLE PRODUCT
