Dr. Frye will know more as to whether he has MBD or not.

Monitor the way he moves. See if he can hop and climb easily or if he seems to have difficulty, drags any limbs, seems uncoordinated, or has twitching-like movements. These will help Dr.Frye to determine more about what is going on.

It is important to provide the calcium/vitaD3 even if no symptoms of tetany or of MBD are visible.

I am not sure if its MBD?
