Hello, I have a 6month old German Shep. and a 4month old rottie. Some how the both of them got to the Osteo-Form 181 and ate every pill in the bottle! That was about 12hrs ago. I called the emer. vet service and they said that worse case sanario is it may cause renal failure in about a week. Both are acting normal, just was wondering if this would effect heart rate seeing that Ca effects the muscles of the body including the heart. Also was wondering about stones that could form from to much Calcium Phos. Any sugestions on what I should do?   Thanks for your time. Stephanie Carpenter
