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 (comparefrocga(“frog”),*picga(“pig”)), appended to a base*dog-,*doc- of unclear origin and meaning. One possibility isOld Englishdox(“dark, swarthy”) (comparefrocga fromfrox).[4] Another proposal is that it derives fromProto-West Germanic*dugan(“to be suitable”), the origin ofOld 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 Englishdock(“stumpy tail”).
In 14th-century England,hound (from Old Englishhund) was the general word for all domestic canines, anddog referred to a subtype resembling the modern mastiff and bulldog.[6] By the 16th century,dog had become the general word, andhound had begun to refer only to breeds used forhunting.[7] In the 16th century, the worddog was adopted by several continental European languages as their word formastiff.[8]

Some of the most beautiful and thus appealing physical theories, including quantum electrodynamics and quantum gravity, have beendogged 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.
