Right now I am doing a Upper Push/Upper Pull/Lower routine alternating 4x/week.
I would like to incorporate Mountain Dog shoulder training.
The areas I want to bring up are delts, glutes, hams, and calves. Tho I dont want to neglect anything obviously.
I want to keep lower day pretty well exactly how I have it now. (deads, squats, hams, lunges, claves, abs)
I am just not sure how to tie everything together if I have a shoulder day?
Any thoughts would be appreciated 
Also perhaps I should go back to an Upper/lower alternating schedule?
as for shoulders, do you really need to change the layout? I mean, why not just do half your shoulder work on your first upper day, and the other half on the second?
For a similar layout to what you have now, have you thought about a vertical upper/horizontal upper/Lower type split. By that I mean, shoulders and pull-up/down type back exercises on the vert and chest/rowing movements on the horizontal. I always felt like splitting my shoulders and chest up allowed me to have a much higher quality workout with each.

I usually do push/pull/legs and it was pretty easy to incorporate Mt. Dog shoulders into it. I would do anything of his for medial and front delts on push day, and the rear swings/destroyers on pull day. I found that as long as my front delts recovered before the next push day, it didn’t hold me back on anything else, even when I pushed it to 5-10 hard sets for medial delts.
ok, thats what I will do then…keep my current routine and just split it up into the push pull days. For some reason I thought it suggested to do it all in one day (I read it through super quick) which screwed me up.
Merci! 
Zraw works with Meadows and if I remember rightly he does all his shoulder work on chest day, so I don’t think it’s really all that essential you give them a whole day of their own.
I personally like to do an upper back/shoulder day just because my shoulders lag waaaaay behind and the extra upper back stuff (I already have a back day) helps keep me injury free.
it was something ( in Zraws thread I think, but cant find) that said this method was great for growth but also for shoulder health? Does that sound familiar or am I just a dreamer?
No reason you can’t do JM’s shoulder stuff in a chest/delts/tris workout. It’s meant to be done after chest anyway, and won’t interfere with tri work.
