In my experience (which is with only bordercollies, shepards, and akitas) when one dog beats up on the other dog excessivly, you as alpha need to step in and punish the other dog for hurthing your spoo. aka put him on time out or pop on his leash.
To help establish who is ontop of who feed,praise, pet the higher dog first then go to the other dog. if the subordinate dog tries to get in on the praise while you are working with the higher ranked dog shove him away without saying anything.
that has always worked for me, but just make sure you are putting the dog who is really higher first, dont decide that you wantt your spoo to be higher up in rank and try putting him first, this will instigate more violence.
