Look closely at your dog's coat and feel its texture. Terms referring to coat texture are: wiry, long-haired, short-haired and curly. Note the predominant color. Colors range from white and off-white to black and everything in between. Color terms include merle, blue, red, brindle, pied (spotted) and roan, among many others. Once you have determined what your dog's coat color and texture are, make a list of the purebred dogs with those same coat colors and textures. For example, if your dog has a short, brindle coat, there are a handful of breeds he could be a partial member of including boxer, mastiff, American staffordshire and greyhound. Narrow down your list by visiting the AKC website and searching under "brindle-coated dogs." Note there are different colors of brindle including black, red and brown.

The terms for ear types are pretty straightforward. Bat ears look like, well, the ears of a bat. Long, pendulous ears are just that, erect ears are straight up and round-tipped ears stand up and are rounded at the tip. It gets a little more complicated from here. Rose ears are folded backwards, button ears stand up and then curve down at the tips. There are other descriptions: filbert, v-shaped, hooded and candle-flame. Take a look at your dog and determine what kind of ears best match his.

The same goes for tail types. In tails, there is the curly-q, bobtail, flagpole, rat, saber, natural and sickle. Looking at your dog's tail. Is it a natural bobtail -- a tiny stump of a tail? Or does it look plush and long, like that of a wolf? Figuring out ear and tail type will help you narrow down even further the breeds of dog that may have gone into your little angel. Look for purebreds with a tail and ears similar to yours.
