Brussel's Griffon...?

[jaycg]

Hi, I'm a new dog owner, of sorts. My girlfriend, who had two little dogs already, went ahead and found a small puppy in a patch of bushes. In a downtown metropolitan area.
Needless to say, she took it on herself to assume that someone else decided they didn't want her, and brought the girl home (after taking her to a vet/animal rescue place to make sure she was all right). Although initially opposed to the idea of a third dog in the house, I've become quite taken with her.

The question we have is--what exactly is she? Exhaustive research has led us to conclude that she's mostly a Brussel's Griffon:

Everything fits, from her shape and features, down to her subtle personality quirks (the endearing and infuriating alike). Except for her coloration. In all my research, I've yet to find that kind of marbled coloration in other Griffons. Does anyone know if this is something indicative of the breed, or if they have any ideas what she might be mixed with?
It's hardly an issue. She's a wonderful dog no matter what her lineage, but I'd be lying if I pretended that I wasn't extremely curious (about as curious as I am as to why someone would leave a little puppy--according to the vet, barely old enough to be on solid food--in the bushes by an office building...).

She looks like an Chihuahua/Border Terrier mix.

We actually spent a lot of time assuming she was Chihuahua/Jack Russel terrier, mixed with any of a number of other breeds. Her body shape and personality led us on that path, but the mystery was about her rounded forehead, large, wide-set eyes and protruding lower lip--not indicative of Chihuahuas or most terriers (I admit that the pictures I put up do not display those qualities well). When someone suggested a Griffon, I looked it up and it all made sense, except for her coloration.

In doing some research, I discovered that the Griffons have been a distinct breed for around 120-130 years, and they are indeed largely descended from the terrier family (dogbreedinfo.com actually classifies them as terriers, though I'm new to the dog world so I don't know the quality of information found there). Her size may be due to some Chihuahua blood, or, because she's most likely not fully grown yet, we might end up scrapping that idea.

I suppose my question really is, has anyone heard of or know about Griffons who have this kind of coloration?

Some Chihuahua have what is called an applehead and they have big round eye and wide-set eyes.

These top two are applehead Chihuahuas.

These last two are Brussels Griffons. They are face are like a Pug. And they do not come in that color.

I don't believe Brussels come in brindle(that "marbling" you described). I'd guess she's a Jack Russel crossed with a Chi or some other small breed. dogbreedinfo.com is not my favorite site. Any info you get on there, or any other online breed list for that matter, should be checked on a site that you know has had extensive experience with the breed. I'm very fond of breed club websites for that purpose. Dogbreedinfo just rubs me the wrong way because they list out all of the "hybrid" "breeds" which are just glorified mixes. Don't get me wrong, I love mixies, but if you breed them on purpose for no reason other than selling them, you shouldn't own a dog in the first place.
