Woofur is proud to bring you a natural, bio-available calcium product that is ideal for supporting bone growth and bone strength. Calcium deficiencies are a common occurrence in companion animals, despite the claim by many pet foods that their diets are “complete." Since Calcium is the foundation block for building strong teeth and bones, you must ensure that your pet is receiving an adequate intake of bio-available calcium when they are young and growing rapidly. Aging pets also benefit from a natural calcium source to prepare their bodies for the changing nutritional needs, especially to balance phosphorus in the system. Many older pets also cannot chew bones as readily as they did in their younger years and need a natural, easily digestible calcium supplement. Woofur's Calcium Eggshell Powder Supplement is a natural calcium source made from free-range eggs. Ingredient: Free-range eggshell Weight: 50g
