If we have a method that returns Dog if it returns anything at all, can we
say:
method foo returns Dog|undef {...}
In a similar vein, if the function reurns a dog or a refernce to an array
, can we use Dog|Array?
And is this legal:
given ($obj){
when Dog: ...
when Array: ...

Yes, but... You'd say that only if you wanted to allow a return
type that can be simultaneously Dog and

Shouldn't that be:
when Dog { ... }
when Array { ... }
Or is there some .when that I have not yet heard of?

Yes, that's how it should be written.
