Sick lizard

Question
I have a 5yr old beard dragon who has passed bloody stool I just pulled out white tissue from it ass plea what is it and what to do help me please

Answer
Hello Tamara,

Wow, that does not sound good.  Are you sure the white tissue was not just urate?
What foods do you feed your dragon?
Do you use UVB lighting & if so what type do you use?  
How often do you use calcium?

It sounds like he may have worms or parasites & needs to get a fecal done on him.  Do you have a vet you can take him to?
