The business originated in 1829 from the establishment of a flour mill in Bridgwater, Somerset, by Joel Spiller.

[2] By 1854, Spiller opened a flour mill in Cardiff with his business partner Samuel Browne.

They were initially marketed as a food for racing greyhounds, but soon gained popularity with pet-owners and became a brand leader in the 1930s.

[4] After its acquisition by Nestlé 1998, the Winalot brand was expanded to include a range of dog foods and snacks.

[9] In the late 1990s, following the BSE outbreak in the United Kingdom, Dalgety entered into a series of disposals and sold Spillers flour milling operations to Kerry Group plc in 1997[10] and its pet foods business to Nestlé in 1998.
