According to this Dec. 2006 report by the USDA Foreign Agricultural Service called the "Gain Report" (Global Agricultural Information Network), there are two companies that dominate the dog food market in China. "Effem Foods Beijing, a subsidiary
of Mars Inc., is the dominant company in the low and medium categories with almost 50
percent market share. Effem produces the brand “Pedigree” in China and it is the dominant
commercial dog food. Pedigree captures the low and mid-price range with both dry and wet
food with many different types, sizes, and package styles. Effem also has several other wellknown
brands. “Royal Canine” is the largest imported brand in terms of sales, the second
largest in terms of overall sales, and the leader of the premium category." (Though Royal Canine is also a subsidiary of Mars, it’s China operation is currently an
independent brand.) Companies with single-digit market share include Nestle, Hills, Purina,
and the Chinese companies Zhangjiagang Lianfeng, Shenzhen Libangda, Shandong Weifang
Pinghe, Chengdu Care, and Yantai China. Currently, Effem is the only foreign company with
significant domestic production capacity, while the other companies import their products".
