We are the first and only company to design a Belly Band Wrap with a paracord buckle. We have a patent on the design US Patent 11622538. These are perfect for male dogs who have been rescued and not yet potty trained; male dogs who are marking or have bladder issues like urine leakage. Most Belly Wraps are made with Velcro closures, the sound of the Velcro being ripped open can be very scary to shy and fearful dogs, not to mention the hassle of things in laundry sticking to the Velcro. We use flannel and cotton which are soft on a dogs skin, we sew a heavy protective flannel lining onto the belly band for added strength and we use a small plastic buckle that quietly Available in 6 adjustable sizes: Use with a disposable liner X-Small (XS) 7.5”- 11" waist (width 3 1/4") Small (SM) 9.5”- 14.5" waist (width 3 1/2") Regular (RG) 13"-17" waist (width 3 3/4") Regular Long (RGL) 15-20" waist (width 3 3/4") Large (LG) 16" - 28" waist (width 5") X-Large (XL) 19-28" waist (width 5")
