He lives at the Boston MFA, where they don't have a date of manufacture listed for him, but they know where he was found (by the great Egyptologist Flinders Petrie, no less). He's from Naukratis, which was a Greek trading post in the Nile Delta established in the 7th century BC. The British Museum has a research project about Naukratis; you can read more about it here. If you search the research project catalog for "dog" you'll see this guy and a number of his fellows pop up, as the project worked with museum collections worldwide. I learned there that he might be a representation of Sirius the Dog Star, whose rising happened around the yearly flooding of the Nile.
