Cockapoo

Cockapoo \KOK-uh-poo\ , noun;
1. One of a variety of dogs crossbred from a cocker spaniel and a miniature poodle

Poodles are fantastic dogs. Smart, cute, and relatively hypoallergenic. So it's no wonder that they are so popular for deliberate cross-breeding -  plus, that name lends itself well to fun portmanteau names. Cockapoo and Labradoodle are supposedly the only poodle-cross portmanteaus to make it into the Oxford English Dictionary so far, and cockapoo is the older of the two. It is first attested in 1960, while Labradoodle dates to 1970.

Personally, I'm a big fan of the Crestepoo (Chinese crested-poodle mix). But, then again, I'm biased.
