We don’t know much about any dangerous animals in Vang Vieng. However, you should be careful with snakes. While it is very unlikely that anything will happen, you should definitely call Vientiane Rescue if you get bitten by a snake. In general, you should be careful about bites. Even if they come from a monkey or dog. Among other things, rabies is a serious danger. The disease has still not been eradicated in Southeast Asia. In the event of a bite, you should definitely go to the hospital. Rabies is always fatal without prophylaxis. As far as we know, there are no tigers, bears or other large predators. There are such animals in Laos. However, we have never heard of them being seen in the Vang Vieng area. The damn mosquitoes are the most dangerous animals anyway. Stay away from them and definitely use mosquito spray.
