The United States accounted for every company in North America’s top 10 pet food businesses by 2025 revenue, according to Petfood Industry’s Top Companies database. Together, the companies generated nearly US$66 billion in reported annual revenue. However, Canada and Mexico were home to several large and growing pet food companies.
The concentration in the U.S. reflects several economic advantages. The United States combines a large pet-owning consumer market with extensive grain, livestock and food-processing industries. Pet food manufacturing also overlaps geographically with agricultural and transportation centers in the Midwest, Plains and South.
The ranking is particularly concentrated at the top. Mars Petcare Inc. and Nestlé Purina PetCare together accounted for approximately 78% of the top 10’s revenue. Adding Hill’s Pet Nutrition brings the three largest companies to approximately 85% of the total.
The Big Two: Mars, Purina anchor U.S. pet food production
Mars Petcare led the ranking with US$29.5 billion in annual revenue.
In May 2025, Mars opened a new Royal Canin dry pet food factory in Lewisburg, Ohio, following a US$450 million investment. Mars described the 450,000-square-foot plant as Royal Canin’s largest dry pet food factory globally and said it would create up to 270 jobs over five years.
The Ohio location illustrates some of the economic factors supporting U.S. pet food manufacturing. The state is connected to Midwestern agricultural and food-processing regions while providing road and rail access to large consumer markets in the Midwest and eastern United States.
Purina PetCare ranked second with US$22.15 billion. The company entered 2025 near the end of a multiyear expansion of its U.S. manufacturing network. Purina previously said it was on track to invest US$2 billion in factory and capital expansion projects between 2020 and 2025, including new production capacity and factory expansions.
Although a subsidiary of Europe-based Nestlé, Purina is headquartered in beautiful, historic St. Louis, Missouri. Found at the confluence of North America’s largest rivers, this location places its corporate operations near the center of the U.S. agricultural and transportation system. Just as it has since Cahokia was the largest city north of Teotihuacan, the surrounding Midwest includes major farming areas, while the Mississippi and Missouri Rivers support movement of agricultural commodities and finished products. Major highways and rail lines, crisscross St. Louis as well.
Hill’s and General Mills develop pet food portfolios
Hill’s Pet Nutrition ranked third with US$4.613 billion.
Headquartered in the Kansas City area, Hill’s operates within a region with significant concentrations of animal health, agriculture and food-processing businesses. The surrounding Plains and Midwest also contain major grain and livestock production areas.
In January 2025, Hill’s presented new and updated Prescription Diet and Science Diet products at the Veterinary Meeting & Expo. Several Prescription Diet products incorporated the company’s ActivBiome+ technology.
General Mills ranked fourth with US$2.5 billion. Its North America Pet business includes Blue Buffalo.
General Mills expanded its pet food portfolio in 2025. In June, the company announced the U.S. introduction of Edgard & Cooper, a European pet food brand acquired by General Mills in 2024. In October, it launched Blue Buffalo Love Made Fresh nationally, expanding the Blue Buffalo portfolio into fresh pet food.
General Mills reported US$2.5 billion in North America Pet net sales for fiscal 2025, consistent with the figure in the Top Companies database.
Midwest and central states support manufacturing
The J.M. Smucker Co. ranked fifth with US$1.63 billion. Its pet food portfolio includes Meow Mix and Milk-Bone.
In February 2025, Smucker announced a leadership change affecting its pet food business. Judd Freitag assumed leadership of U.S. Retail Pet Foods and Sweet Baked Snacks effective March 7.
Smucker is headquartered in Ohio, adding another major pet food business to the Midwest and eastern U.S. concentration of manufacturers and corporate operations.
Diamond Pet Foods ranked sixth with US$1.5 billion. The family-owned company operates manufacturing facilities across several states, including Missouri, South Carolina, California, Arkansas, Kansas and Indiana. Diamond has also reported construction of an additional pet food manufacturing facility expected to be completed in 2025.
Simmons, Freshpet and Alphia represent different production models
Simmons Pet Food ranked seventh with US$1.25 billion.
Arkansas-based Simmons Pet Food is part of Simmons Foods, whose operations include poultry, pet food and animal nutrition. The company describes itself as the largest supplier of store-brand wet pet food in North America.
That corporate structure creates a direct connection between pet food and the animal-protein industry. Arkansas and surrounding states form one of the country’s important poultry-producing and processing regions. Simmons has pet food operations in northwest Arkansas, Emporia, Kansas, and Dubuque, Iowa.
Freshpet ranked eighth with US$1.102 billion. The company specializes in refrigerated pet food, requiring a production and distribution system different from conventional shelf-stable dry and wet foods.
Freshpet continued developing its Freshpet Kitchens South manufacturing campus in Ennis, Texas, during 2025. The location provides access to a large Texas consumer market as well as interstate transportation routes serving other regions.
Alphia ranked ninth with US$1 billion. The contract pet food manufacturer expanded its production network in March 2025 by acquiring the manufacturing operations of a newly constructed facility in Pittsburg, Texas. Alphia said it planned additional investment in the facility to increase capacity and capabilities.
The Texas location places another major pet food manufacturing operation within a state that combines animal agriculture, food processing and extensive highway and rail networks.
Wellness expands wet cat food portfolio
Wellness Pet Company completed the top 10 with US$720 million.
The company expanded its wet cat food offerings in August 2025, announcing more than 20 additional products. Wellness said the introductions brought its wet cat food assortment to 93 varieties.
Wellness operates U.S. manufacturing facilities in Arkansas and Minnesota, giving the company production locations in regions with established agricultural and food-processing industries.
Canadian and Mexican companies remain outside top 10
Although no Canadian or Mexican company reached North America’s top 10, Petfood Industry’s Top Companies database shows sizable pet food businesses headquartered in both countries.
Champion Petfoods was Canada’s highest-revenue company at US$265 million, followed by The Crump Group Inc. at US$64 million.
Champion, maker of Orijen and Acana, was founded in Alberta and operates its NorthStar manufacturing facility in Acheson, near Edmonton. Its location connects the business with western Canada’s agricultural economy and transportation routes serving Canadian and U.S. markets. Champion is now part of Mars Petcare, complicating comparisons with independently owned Canadian companies.
The Crump Group produces Crumps’ Naturals, Caledon Farms and Dog Delights. The Ontario-based company also operates a facility in North Carolina, giving it manufacturing operations on both sides of the U.S.-Canada border.
In Mexico, Grupo Belenes, commercially known as PRONUA, led with US$240 million, followed by Campi Alimentos S.A. de C.V. at US$55.6 million.
PRONUA is based in Zapopan, part of the Guadalajara metropolitan area in Jalisco, an important livestock, food-processing and manufacturing state. The company began in animal feed before expanding into pet food.
Campi also has roots in animal nutrition and is backed by Grupo Bachoco, connecting its pet food operations with a larger poultry and feed business.
Together, the companies illustrate the broader North American industry beyond the U.S.-dominated top 10. Canadian manufacturers benefit from agricultural resources and integration with the U.S. market, while Mexico’s leading companies have strong ties to livestock, feed production and domestic food-processing industries.
U.S. scale defines North American ranking
North America’s top pet food companies show a strong national concentration. All 10 of the region’s highest-revenue companies in the database are headquartered in the United States.
That dominance reflects more than the size of the U.S. pet market. Manufacturers operate within an economy that combines large supplies of grains and animal proteins with extensive food-processing capabilities, transportation infrastructure and a national retail and distribution system capable of supporting high production volumes.
Canada and Mexico add significant manufacturing, agricultural and consumer markets to the regional industry but do not approach the scale of the largest U.S.-based companies. Cross-border ownership, sourcing and trade nevertheless connect the United States, Canada and Mexico within a broader North American pet food supply chain.
