Belly bands are like diapers for boys. It's a piece of fabric/cloth that you use a maxi pad in and wrap it around your boys middle section preventing him from lifting his leg and peeing on everything in your house.
I have seen them at Petsmart and I thought they were spendy. I agree with bren, you can order way nicer ones for a lot less from someone on YT.
P.S. my opinion is that there are NO stupid questions |
