Our Pooch Post has a patented design which rotates 360 degrees to prevent tangling. Install several outside sleeves for multiple locations to protect your yard from damage. The heavy metal construction of the dog Pooch Post will hold breeds up to 150 lbs. No need to move the Pooch Post before mowing.....simply pull the inner sleeve out of the post! The most inexpensive way to ensure that your pet is safely within your yard.
