'Participation in home exhibitions encouraged dog-food manufacturers and breeders to adopt new strategies of self-presentation. At the exhibitions, manufacturers portrayed themselves as exemplars of middle-class respectability and scientific domesticity as much as providers of alimentary produce... Companies also highlighted the scientific nature of their manufacturing processes. Merrett’s Ltd. of Cardiff gave a “practical demonstration of the method of manufacture” of their new “Rayrusks” (which occurred under “ultra violet rays”) at the Crufts show of 1933.” [note: '“The Exhibit of Merrett’s Ltd., of Cardiff, at Cruft’s Show,” Our Dogs, no. 90 (24 February 1933): 502.
