My bearded dragon Zym is usually a sweetheart even though he can be hyper. In the beginning, my dog would sniff near my dragon but never did anything. She soon learned to leave Zym alone so I’d let them both be outside in the backyard. (I’d watch Zym 100% of the time) Today, Zym ran really fast over to my dog who was sleeping, bobbed his head, and BIT HER! My dog woke up frightened but only looked at Zym. Luckily, she is a good and old dog so she didn’t do anything. I moved Zym away, pet my dog, and took Zym inside. Is this normal? A bearded dragon who made an effort to run over and bite a sleeping dog who has done nothing?
