Penny's also a fussy eater (except where Sunday dinner is concerned when she just woofs down any leftovers as if she was starved) and I've given up trying to feed her kibble (Burns) for breakfast so she has Nature diet, which she loves. At tea time she's usually hungry enough to eat most of the kibble.
HOWEVER when we got her, a dear friend gave us two massive bags of Royal Canin Cocker Spaniel 25. Unfortunately it was for adult dogs, so we've been saving it until now. Well yesterday I opened it and the dogs just went crazy! Penny finished every last morsel ( much to Jonny's disappointment), the same again this morning, and she's been showing me the cupboard where it's kept ever since.
It certainly has a strong smell and the kibbles are slightly moist, which may make a difference. Trouble is, I've got two more big bags of Burns to finish up...
