Animaroo has a nice overview of the puggle dog breed that's worth a read from anyone who wants to learn some of the basics about these amazing animals.
In addition to providing a solid encapsulation of the breed, its appearance and tendencies, the article also notes that puggles became the most popular "designer dog" breed after the 2005 media attention that was paid to them.
Excerpt:
"Puggle owners praise the personality of the breed as its most valuable pet trait. They are playful animals and clown-like in disposition. They tend to have short bursts of energy, then quickly tire, take a short nap, then want to play again. These playful tendencies can make them slow to train, and may also manifest in hyperactivity (a trait common to both Beagles and Pugs)."
