For people who simply cannot get enough of that adorable flat snout, those lovely if bulging brown eyes, that squiggle of a tale, and that incessant symphony of grunts, snorts, and wheezes, there is Pug Sunday. The first Sunday of every month, a crowd of pug lovers convenes at the top of Alta Plaza's north hillside around 2 p.m., with pug festivities in full swing until about 4 p.m. All dog breeds are welcome so long as they're pug friendly -- which they better be, given that 50 to 75 of the stocky little pooches are running about making new friends or just dutifully hanging out with their caretakers. Some people lay down a blanket and enjoy a picnic (with a few furry fans always on the periphery), while others snap photos and exchange pug lore. And if you're in the market to buy, you may find a pug pup accompanied by its breeder. An absolute must for hound lovers!
