Pet Care

Dr. Fox:
...Growing pups, especially of the giant breeds, need ample dietary calcium. But excessive levels can interfere with the uptake of other essential minerals, so a balanced multimineral and multivitamin supplement is advisable.

As I point out in a review at my website, some sources of calcium, like bone meal and oyster shell, can be high in toxic chemicals such as fluoride and lead. These are best avoided............
