I have taken on the trimming aspect of Merlin's feet since the two failed farrier attempts. 
I have only be doing rasping and taking back the toes, mostly on his fronts and reducing the flaring. 
however, I am not certain as to how much more and where on the hoof he needs trimming.

Hi Jean, 
Kudos to you for taking active role in your horses hoof trimming. I am not sure where you are located, but i highly recommend Ida Hammer for learning about trimming your own horse. Her website is

many of the trainings and information are online and i believe you can order "model hoofs" to practice on. I am attending her 3 day workshop for the 3rd time here in Michigan in a couple weeks. I took her trainings  twice and this is my 3rd. I always learn something new and good to get refresher. I have been trimming my mare for a couple years after not getting good results from farrier. 

good luck
