My pug dog Angel doing tricks. Pugs are smart dogs and can be trained to do just about anything - for food of course! Ive had a beagle, lab, cocker, mut, and now a Pug. And by far, the Pug is the most enjoyable, loving, smart, and friendly dog out of all of them. The other dogs were great but Pugs are the best companion dog. She just wants to be around people.
