if your angels are always 0 and 90 then use \ncloop, it is easier ...

\begin{pspicture}(5,5)
\pnode(1,3){A}\pnode(5,3){B}\psdot[linecolor=red](A)\psdot[linecolor=red](B)
\ncloop[angleB=180,loopsize=1cm,arm=1cm]{A}{B}
\rnode{A}{NodeA}\hspace{4cm}\ovalnode{B}{NodeB}
\ncloop[arm=1cm,angleB=180,loopsize=1.5cm,linestyle=dashed]{A}{B}
\end{pspicture}
