My bearded dragon has been treated for a large amount of parasites. The vet was even very surprised by the amount he had. After the last treatment, I haven't been able to go back in for a check up. Lately his meal worms, carrots, and collard greens all come out basically the way they go in. he can't seem to digest the exoskeletons of the worms. A ton of the exoskeletons come out when he poops. Today he even pooped out a full piece of a carrot and a whole leaf of a collard green. This has been happenening for about 2 weeks. He got the treatment for the parasites first over a month ago and the most recent treatment was 3 weeks ago. What is wrong with my little guy??
