The Dr. Goodpet Story There"s a real health epidemic affecting our pets. Too many dogs and cats get sick and die before their time. That"s what health writer Martin Zucker learned from veterinarians and breeders while researching five different books on pet health. In 1984 Zucker teamed up with Louis Gottlieb, a businessman with many years of experience in the pet industry, to create Dr. Goodpet Laboratories, a part of their family-owned and operated company Very Healthy Enterprises, Inc.. Starting with a single product in 1984, the company has grown steadily and now sells over 30 products, with new items being added all the time to thousands of customers nationwide, including veterinarians, breeders, groomers, trainers, pet owners and leading pet and health food chains. Dr. Goodpet"shomeopathic remedies have the distinction of being the first in the U.S. made exclusively for pets. Based on advanced European combinations used for many years, these remedies help relieve such problems as itching, flea-bite allergies, scratching, skin conditions, motion sickness, hyperactivity, diarrhea, foul breath, ear infections, pain and stiffness from arthritis, and minor eye irritations.
