The calcium / phosphorus ratio of CANI-CAL is 1,2 : 1, which is generally accepted as optimum for dogs.
A high dietary calcium content or a vegetable protein-based diet (e.g. dry dog foods all of which are largely soya) can dramatically increase the zinc requirements of the dog. In addition, recent studies in man suggest that the inclusion of soy protein in a diet also reduces the absorption of iron. Both of these essential nutrients (iron and zinc) are present in CANI-CAL in adequate quantities. Iron is present as ferrous fumarate which is well-absorbed and, at 5mg of zinc per 5g dose, CANI-CAL more than provides for the increased zinc needs of the dog.
The base of yeast and real cheese and liver ensures palatability making it most acceptable to dogs of all ages and types.
