Users and admirers (and even unknowing beneficiaries of the effects of) UnderEase (the odor-trapping underwear with a removable charcoal filter, which earned its inventor, Buck Weimer, the 2001 Ig Nobel Biology Prize) may already be aware of a recently-announced device for dogs.
Uses our famous activated charcoal cloth (washable and reusable)! A starter hole is placed in the cloth in order to help you locate the suggested tail hole. Carefully measure tail and cut-out hole to proper size.
(Thanks to Investigator Julia Lunetta for bringing this to our attention.)
