Oreo
[ˈɔːri.oʊ]Oreo is a biscuit, and as a dog name it comes from the coat: a black-and-white dog looks like one. The biscuit's own name has no agreed origin, and the two explanations usually offered for it are both unproven.

The name comes from the coat, not the biscuit
Nobody names a dog Oreo because they are fond of biscuits. They name it Oreo because the dog is black with white markings, and an Oreo is a dark disc with white in the middle. The name describes a colour pattern, and it is one of the commonest descriptions there is — with Domino, Patches and Pepper it forms a short list of defaults for black-and-white dogs.
That shapes the whole character of the name. Oreo is not a name with a history you are invoking or a meaning you are borrowing. It is a visual joke, and it is a very efficient one: everyone who meets the dog will understand it instantly and without being told.
A biscuit with a name nobody can explain
The biscuit was introduced by Nabisco in 1912, as an answer to the Hydrox, which Sunshine Biscuits had launched in 1908 and which Oreo eventually displaced almost entirely. The sandwich cookie as a form is older than both of them.
What nobody knows is where the word came from. Nabisco never explained it and no document has settled it. The theory you meet most often is French: or means gold, and the first Oreos were sold in gold-coloured packaging. The second is Greek: ōraios, meaning beautiful or well-made. There are others involving Latin and the shape of the letters. All of them are guesses, and the standard reference works say so.
If you have seen a page stating that Oreo means "beautiful" in Greek, it is repeating one of those guesses as though it were a fact. Our own listing carries the same claim in its background note. The defensible answer is that the origin is unknown.
What the name does at the dog park
oh-REE-oh, usually with the stress in the middle. It opens on a vowel, which is the thing to think about: names that begin with a vowel are harder to hear at distance than names that begin with a consonant, because there is no edge for the ear to catch. The ending is a clear -o, which is good — an open vowel a dog can hold.
The name is also, by a wide margin, most often given to dogs that are black and white. Oreo is closer to a category than a name, and if you take a black-and-white dog called Oreo to a park, the odds are good that somebody will tell you they had one just like it. That is only a drawback if you wanted to be the only one.
One thing worth deciding in advance: whether you are willing to have the conversation about the biscuit, because you are going to have it several hundred times.
Common questions
Does the name Oreo mean anything?
Not in any way that can be established. The biscuit's name has no documented origin; the French "gold" and Greek "beautiful" explanations are theories rather than translations. As a dog name, Oreo means black and white.
Is Oreo a boy's name or a girl's name?
Neither. It is a description of a coat, so it gets applied to any dog wearing those colours. Our listing files it as unisex, which is accurate.
