This discussion leads me to a question.

 

Background:  When lowering the heels I slowly back them up but don't lower them any shoter than the frog.  Still the frog begins to develop that crack in the sole sulcus.  Once this crake develops it seems like hooves are comprimised.  Now I am not big on trimming the frog, but maybe I should and have just been scared to do so.

 

Question:  Should a trimmer cut portions of the frog off towards the back of the heel when attempting to "open"/lower the heel?

 

Thanks,
