What does a cabal have to do with a gelded horse? And why were so many dogs in (fictional) literary works set in Merrie Olde England named Cabal?

Well, the cabal which means a group of conspirators is from Hebrew qabbalah 'received knwoledge; tradition' via Latin cabala. Not sure about the canine names; tradition perhaps. Any way, it's a coincidence.

Ceci n'est pas un seing.
