The Helvetia Milk Condensing plant of New Glarus, purchased in 1910 from the New Glarus limburger cheese factory, contracted with 15 patrons to haul milk. It supplied 5,000 pounds during the first few months and increased to its peak of 160,000 pounds daily in 1922. Helvetia Milk Condensing was renamed the Pet Milk Company in 1923.
