I had gone to school today at 7 this morning after I had taken care of my bearded dragon I changed his food and gave him fresh water. I had gotten home around 4 and took care of my dogs, after I finished I went into my room and saw my bearded dragon lying in the ground with his stomach being very puffy and had red stuff coming out of his mouth and a red bubble on his rear end I tried to look around but I could not find anything about what happened. He was around 6-7 years old I had gotten him 5 years ago and he had already been an adult of a while when I had gotten him. I am not quite sure of his age exactly.
Poor guy. It looks like he was bleeding quite a bit. Possibly organ failure of some sort. It's hard to tell without having a necropsy done. What was his primary diet? What do you have in place for his lighting and tank setup?
