Morphological, biochemical analysis and bone turnover markers (BTM) in blood and urine were performed for six dogs twice, in the start of the research, and in the end after calcium (Ca) rich additives, without phosphorus (P), dosing for one month per os. All dogs were clinically healthy at the start and in the end of work. No significant changes were observed regarding to blood morphology. The level of Ca and P in blood before Ca additives dosing was in physiologically reference values in five from six dogs. One dog had hypocalcaemia and hyperphosphatemia in the start of the research. At the end of the research level of Ca was increased for all dogs (p is less than 0.05), while P were decreased in four from six dogs and was also in reference values. Osteocalcin in blood decreased in all dogs (p is less than 0.05) which show us decrease of bone regenerative processes. The dog with expressed hypocalcemia at the start of the research, were with considerably increased marker of bone resorption marker β-CTx at the end. In conclusion whereas all dogs were clinically healthy in the end of the research, changes regarding to BTM in blood are important point to evaluate influence of the treatment with Ca rich additives to bone health. Although, the level of Ca increased in blood, the results of BTM let suggest about negative effect on bone health. The need for P organism compensates with P absorption from their own bones, thus reducing bones quality. Using feed additives for dogs definitely must follow Ca and P proportion.
