Canidae plus raw.
Canidae has been on the Whole Dog Journal's Top Ten Dog food list for several years and I'm just lucky that a breeder here imports it. No more expensive than most premium brands and I'm now very happy with my Cavalier's condition.

When showing, working & breeding ESSs I used a mix of Eucanuba, Super Coat and Pedigree, just following my old vets advice of not feeding just one 'complete' food. Worked well for me. ymmd.
