Some informal, pet-focused community events are advertised under playful names online, but there is no verified single island-wide festival by this name in the sources. Organizers and schedules vary by event; check who is running the specific date you are considering. Pet-related fundraisers and adoption drives happen in different parts of Bali at different times; verify date, venue and host organization on an official listing. Stall types and activities depend on the specific event, check the program on the host's official page. There's usually food for sale too, plus a stage with music playing at a reasonable volume rather than a full concert rig.
Kids are welcome, and most families treat it as a relaxed outing rather than a big event day. Bring a hat and water bottle, since these festivals run outdoors in the heat of the day. If your child is small or easily overwhelmed, arrive early before the crowd and the dog traffic build up, the same approach that helps when sizing up the Bali Kite Festival with young kids. The main thing to watch is strange dogs reacting to strange kids. Not every dog there is used to a toddler grabbing its tail, so keep little ones close and know what to do if a child is bitten by a dog or monkey anywhere in Bali, festival or not.
Bringing your own dog works well if it's already comfortable around crowds and noise, and friendly with other dogs it doesn't know. Keep it leashed the whole time and bring your own water. Watch for overheating too, especially on hot pavement or in direct sun, since a festival means more standing around than a normal walk. These festivals are also a genuinely good socialization opportunity for a dog that only just arrived in Bali with your family, since it gets used to crowds and other animals in a controlled, friendly setting. If you're still working through the logistics of bringing a pet into Bali, a calm, supervised outing after your dog has settled in can be a lower-stakes way to see how it handles crowds, choose a venue and time that match your dog's temperament.
