Ety Fefer, a Peruvian artist whose work sends her traveling the world, hates leaving her dog behind.

So she brings him along.

Cerbero, a cute white sort-of-poodle, is now 15 years old and has been on the road with Fefer for the last four years.

“I always imagined that he dreamed of traveling the world,” she said. Together they’ve been to Paris, Cannes, Dusseldorf, Pompeii (Italy), Piran (Slovenia), San Francisco, Monaco, Oaxaca, Vegas, New York, Mexico City, Jamaica, Torino, Madrid, Florence and many more.

He never barks, or very rarely does, except when left alone in the house. The mutt is such a good sport, Fefer said, that traveling with him flows seamlessly and people tend to love him – some will start to take pictures of him, too, charmed by her fluffy little guy.

When she knows they are off for a long day of walking, Fefer brings a wheeled backpack and pulls him along. Sometimes he shares the stroller with her 2-year-old son, she said.

“They are like brothers,” she said. Her son, Darko, and her partner also travel with her everywhere.

Not only have Ety and Cerbero been to countless cities together – but she sometimes also smuggles him into movie theaters and other venues, such as the circus. There he always stays put, Fefer said. “He stays in his bag and no one notices; he understands that he cannot leave the bag and stays happily sleeping peacefully.”

Fefer named her dog after Cerberus, the Greek mythological character that supposedly protects souls in the underworld.

“I feel that Cerbero is like a magical, fantastic character,” she said, “he prevents me from going to the dark side.”

Fefer, 41, is in New York City these days with an exhibit of “Los Grumildos,” her expressive marionettes that she says are like “a portrait of the dark world made with love and sense of humor.”

Meanwhile, Cerbero and his travels have attracted attention around the world and is the subject of a blog, Cerbero on the Road, where Fefer keeps a selection of her mutt’s sittings.

Next off, she said, will hopefully be “someplace in Asia,” where the pair hasn’t traveled to yet. China would be difficult, she reckons, but Hong Kong or Singapore could fit the bill.
