Fresh chicken is the first ingredient, combined with chicken meal, whole grain brown rice, and cracked pearled barley to provide high-quality protein and energy. The formula includes prebiotic and probiotic fiber sources with live microorganisms (Lactobacillus plantarum, Bacillus subtilis, Lactobacillus acidophilus, Enterococcus faecium, and Bifidobacterium animalis) to assist the sensitive digestion needs of small breed dogs.

The recipe contains fish meal and flaxseed as additional protein and omega-3 sources, plus functional ingredients like dried chicory root (prebiotic), carrots, apples, cranberries, and dried kelp for added nutrition.
