Dogs, wolves and foxes also have a lot of cultural significance basically anywhere you go that has them. To give you an example of how deep this goes, I'll flash my nerd card and talk about etymology.
In linguistics, there is a concept known as taboo deformation, which describes when a word is intentionally altered so as to avoid saying the original, as doing so would violate a social taboo. A good modern example of this is using "darn" instead of "damn." This phenomenon is not new by any means; consider the many names of God in Judaism. Yet etymologists studying the roots of words in various Indo-European languages uncovered something even more peculiar: A pattern of taboo deformation influencing the evolution of certain words starting before the introduction of writing across numerous branches of the same family tree of languages. Three words in particular stood out.
"Fox," "wolf," and above all, "bear." These are what the ancient Indo-Europeans feared, before they were Hittites, Scythians, Indians, Persians, Greeks, Celts, Romans, Tocharians, Norsemen, Slavs, Armenians, Romani, Englishmen, or anything else you can name. Our relationship with canids (and mammalian predators more broadly) is burned into our very language.
