STERLING, Ill. — Wahl Clipper has introduced a new line of all-natural pet cleaning products, including dog deodorant and easy-rinse shampoos. The deodorant is designed to be sprayed on dogs — with a strong but not overwhelming scent — and then to dissipate, taking the dog’s odor with it. The new shampoo was designed with humans in mind; Wahl’s director of North America consumer sales Audie Rudiger told DSN, “the first thing people do when buying shampoo for themselves is to smell it.”
