Can a bearded dragon go in water like a bathtub with small amount of water?
Bearded dragons are capable of swimming. However, the water should be kept shallow so that it doesn't have to. The bath water should be at least up to the dragon's elbows.
mine do with a small amount of warm water when I clean their tank
YES!!! They dont really like it but its a good show. My cousin and I did it with hers. Its really funny. The MAX you should put the water to is their neck/chest
