16 OZ Dog Calcium Supplement with Phosphorus and Vitamin D, Calcium Powder for Dogs, Promotes Optimal Bone Development for Puppies Aged 8 Weeks and Up, No Color

Bought 2 cans of this calcium 20 days ago. It was kept in a cabinet, while the first can was used.First, when I introduced it to my dog's food, they both refused to eat it based on smell. Then when they tasted it, they made a face.They've had dozens of supplements over the years, including 3 different brands of calcium so I don't know what about this didn't suit them. But they got used to it.But then I pulled out the 2nd can and the powder was moldy. Had to throw it out. Will NOT be buying this ever again.
