Hello,
Wow, poor dragon, I am so sorry that happened.
He needs immediate ER/VET care as soon as possible. I am sure he is likely in a lot of pain, since
he has a
black beard. What type of dog bit him? Did he bite him directly on his head or on some other
part of his body?
Please let us know how he is doing. Do your best to keep him comfortable tonight, stress free, etc.
I hope that he is going to be ok.
