The original meaning seems to have been a common dog, as opposed to a well-bred one, or something like 'cur', and perhaps later came to be used for stocky dogs. Possibly a pet-form diminutive with suffix -ga (compare frocga(“frog”), *picga(“pig”)), appended to a base *dog-, *doc- of unclear origin and meaning. One possibility is Old Englishdox(“dark, swarthy”) (compare frocga from frox).[4] Another proposal is that it derives from Proto-West Germanic*dugan(“to be suitable”), the origin of Old Englishdugan(“to be good, worthy, useful”), Englishdow, Dutchdeugen, Germantaugen. The theory goes that it could have been an epithet for dogs, commonly used by children, meaning "good/useful animal".[5] Another is that it is related to *docce(“stock, muscle”), from Proto-West Germanic *dokkā(“round mass, ball, muscle, doll”), whence English dock(“stumpy tail”).
In 14th-century England, hound (from Old English hund) was the general word for all domestic canines, and dog referred to a subtype resembling the modern mastiff and bulldog.[6] By the 16th century, dog had become the general word, and hound had begun to refer only to breeds used for hunting.[7] In the 16th century, the word dog was adopted by several continental European languages as their word for mastiff.[8]

Some of the most beautiful and thus appealing physical theories, including quantum electrodynamics and quantum gravity, have been dogged for decades by infinities that erupt when theorists try to prod their calculations into new domains. Getting rid of these nagging infinities has probably occupied far more effort than was spent in originating the theories.
