References to the dog can also be found in Ancient Greek and Roman literature. Aristotle mentions the dog around 370 BC. Early writers attribute its origin to Melita, however there were two islands named Melita at that time with one being in the Mediterranean and the other being in the Adriatic sea near Dalmatia, which confuses where the dog originated from. The Maltese does not shed, and is therefore a good choice for people with dog allergies. They can exhibit signs of tear-staining. Any suggestion of kinkiness, curliness, or woolly texture is objectionable. Maltese are a pure white, yet sometimes dull gold fur will grow behind their ears and on their back. Light lemon on the ears is permissible, but not desirable.
