巴西人字拖品牌Brizza推出世界上第一款不可咀嚼的人字拖鞋，这款人字拖鞋有什么特别的作用？

Created by Brazilian flip-flop (人字拖) brand Brizza, the world’s first unchewable flip-flops are made with the most bitter substance known to man.

Dogs’ love for chewing footwear is well documented. Puppies do it to release pain as their teeth grow, other dogs do it out of boredom or some form of stress, and some just like chewing stuff. This habit puts them at risk of very serious gastrointestinal (肠胃的) problems. Data shows that in a third of gastrointestinal surgery procedures to foreign objects from the intestines (肠道) of dogs, the ingested substance is footwear rubber, mostly from flip-flops. Seeing as this can cause life-threatening problems for the poor animals, flip-flop brand Brizza decided to create the world’s first unchewable flip-flops.

How to go about making flip-flops that dogs wouldn’t chew? Ideally, the solution was that they could include something that dogs hated. That’s where the expertise of pet-food brand Pedigree came into play, as they were the ones who suggested using denatonium benzoate (苯甲地那铵), the most bitter chemical in the world.
