First off, you need to teach him his name.
So out him on a leash and don't pull in it.
Have treats
Say his name and put the treat where he can see & smell it
When he comes to get it say "good Spartacus"
Will take about a week
Also remember dogs are a simple minded animal so you don't have a convo command so it wouldn't be Spartacus come over here it would be "Spartacus Come"
So you get attention with name
You get results by the command
But you must teach the command
