I have a new PM-1236T and tried to use a lathe dog to turn between centers and the tongue on the the dog would not reach the face plate. I am using a MT 5 reducer and MT 3 center. Has anybody had this problem and how did you solve the problem?

You could make a driver stud that fastens to and projects from the faceplate, long enough to contact the lathe dog, or weld an extension to the tail of the dog.
 
Make a drive center that’s not tapered and use it in your 3-jaw. On my PM1340GT, this is how I do it. Link.
 
A center that is simply made straight is best made with a shoulder that won't allow it to be pushed back in the chuck, and if used in a 3 jaw chuck, likely will need to be trued up before each use when it has been removed from the chuck. The best setup is to have a driving plate made to drive lathe dogs rather than a faceplate, and a center that is the proper length to allow the dog to engage the slots in the driving plate, and best that the center is soft enough to allow truing up with a tool bit, also the bushing and the center and the spindle nose should be marked so that the center is in its most concentric location when removed and re inserted.
 
I prefer to use a shop-make stepped drive center in the 3-jaw and true up the taper every time mounted. There is no "best way". To each their own.

This is key, I had an issue with a center that was too long to allow the dog tail to engage the drive plate.
