Natural Pet Center is proud to carry Bio-Groom in Fargo, North Dakota. In 1971, a brilliant, determined chemist named Claus Pohl was on a mission. He had a makeshift lab down in the basement of his home in Longview, Texas. A friend and groomer had asked if he could develop a flea and tick pet shampoo superior to what was on the market. Claus took the request seriously, and the rest is history!
