A nutritious dry food for a tumor-bearing pet, comprising a spindle. The ingot includes an upper surface, a lower surface opposite to the upper surface, and a surrounding surface that engages between a periphery of the upper surface and a periphery of the lower surface. The ingot has a plurality of host particles, and most of the black yeast beta glucan particles mixed with the host particles. For pets with cancer, the nutritional needs are different due to physiological metabolic changes, so dry food must be designed according to the nutrients needed for the tumor. The most important thing for anti-tumor cells is to improve the immune function of autonomic cells. The β-glucan cultured by black yeast contains a large number of polysaccharide molecules that can enhance the basic functions of cells, so it can strengthen the basic functions of immune cells and optimize the immune system of pets. Help with the pets given by the diet.一種罹患腫瘤寵物的營養乾糧，包含一錠狀體。該錠狀體包括一上表面、一相反於該上表面的下表面，及一銜接於該上表面之周緣與該下表面之周緣間的環繞面。該錠狀體具有多數主體顆粒，及多數與該等主體顆粒共同混合的黑酵母β葡聚醣粉粒。對於罹患腫瘤寵物而言，因生理代謝改變造成營養需求不同，故必須依罹患腫瘤時所需要營養來設計乾糧。對抗腫瘤細胞最需要的就是提高自主細胞免疫機能，而黑酵母所培養的β葡聚醣含有大量能提升細胞基礎功能的多醣體分子，故能強化免疫細胞的基礎功能、優化寵物自身免疫系統，由飲食上給予寵物所需幫助。
