[nagdu] U.S. Source for Toileting Harness?

[Dani Pagador]

Hi, Everyone.
The organization that helped me get my last guide dog is no longer
carrying toileting harnesses; the office person says handlers are now
getting them from an online U.S. source, and she doesn't know where.
I've Googled and can't find anything re toileting/relieving harnesses.
Does anyone know of a source in the U.S. where I can get a replacement
relieving harness?

Thanks,
Dani
