This occurs when they are excited and run about flailing their legs out to the side and into the air. This often happens at my farm when a big noisy truck rushes down the road. The camels get very excited and react. You can only run for cover when this occurs in order not to be kicked. It is best to train them that they can never do this when you are present.
Camels can spit as can any animal in the camelid family.
This family of animals includes the Bactrian and Dromedary camels, llamas, alpacas, guanacos and vicunas. Or they may spit at a person, which is unusual, out of frustration or as a defense, feeling that a person may bring it harm. One day a man brought a little boy to visit my camel, Gobi. Gobi is very loving, likes to nuzzle, and is gentle with children. The man asks if the little boy could feed Gobi carrots .
