Previous studies at Michigan State University have shown that 0.1‐10 ppm of cadmium and 1‐25 ppm of chromate in drinking water had no effect on the growth rate or food consumption of rats over a 1‐year period. In addition, no pathologic changes in blood or other tissues were noted in these animals. Although these studies indicated that small concentrations of cadmium and chromate were nontoxic, the experiments were limited, for only one species of animal was used and the total period of consumption of the elements was 1 year. The present study was undertaken to ascertain the effect on dogs of small amounts of cadmium and chromate ions in drinking water administered over a 4‐year period.
