Bark Ave Pet Supplies is proud to carry Bayer in Harleysville, Pennsylvania. Because they can't tell you where it hurts. Your pet may not be able to say what's wrong, but they have ways of showing it. They're so expressive, and Bayer Animal Health is working to make sure they stay healthy. We're as passionate about animals as the families and businesses that rely on us, because healthy animals make the world a better place.
