BOISE, Idaho (AP) — Attention pet owners: A company you've never heard of wants you to stop buying prescription medicines and supplements for your dog or cat from your veterinarian and buy its products in stores instead. PetIQ, of Eagle, says it is the first and leading seller to retail stores of premium, "veterinarian grade" pet medications and health products that you could buy previously only through veterinarians. Christensen, a Centennial High School and Boise State University graduate and a former executive at Albertsons and other companies; and Scott Adcock, a marketing expert and former owner and CEO of Nicklaus Golf Centers International. "Pet owners can typically buy our products from retailers at a 20-30 percent savings compared to the prices charged by veterinarians, and can save as much as 50 percent on our proprietary value-branded products, which contain the same active ingredients," the company said in its prospectus for investors before Friday's initial public offering. A bill called the Fairness to Pet Owners Act of 2017 could speed the migration of pet medications to retailers by requiring veterinarians to give pet owners prescriptions that they can fill more cheaply at retail pharmacies, PetIQ says. Demand for shares exceeded supply at opening, so trading opened at $16 a share, the upper end of the anticipated range of $14-16.
