German Shepherd dog

Hello All:

I have an 8 month old all black working line GSD who I started giving PSD Complex II probably about 2 months ago due to a stubborn right ear that didn't seem to want to stay up.  Anyway, ears are both up now and she appears to be past this issue.  My question now is should I continue the PSD or would I be over doing it now from a health perspective.  Too much vitamins? The manufacturers description of its product indicates for dogs with   "structural bone growth problems in fast-growing large breed dogs and small, stocky, long-bodied canines when bone deficiencies are evident."  It also says, "May be helpful in the prevention of hip dysplasia."  My pup is currently on a diet mix of Abady Raw and Evo dry.  Any thoughts?  Thanks in advance for your advice...
