puppy foods are formulated to supply all the nutrients required to sustain normal
growth—provided the puppy or young dog consumes the puppy food as the sole
or main source of calories. More vitamins and minerals added to the diet will
not add more substance or coat to the growing dog.
When calcium, phosphorus, and vitamin D are given in excess of a dog ’ s
capacity to use them, growth and development can be adversely affected.
Overdosing with vitamin D causes bones to calcify in an uneven fashion. In
addition, calcium may be deposited in the lungs, heart, and blood vessels.
Vitamin and mineral supplements are most effective when given to elderly
dogs with poor eating habits who may have developed a specific deficiency. The
appropriate dose of any supplement should be determined by your veterinarian.
