Why doesnt my bearded dragon want to eat?

What do his eyes look like, runny, any discharge? Maybe he’s not getting enough vitamins, a deficiancy, or too much could easily be enough. Do you gutload his live feed? It’s optimal to do so four hours before feeding, so that the nutritional value is passed along. Crickets are very low grade staple food, try Dubia roaches, they can’t fly, females have no wings, they are horrid climbers, they cannot scale glass - breeds easily, and are very good considering the high meat to shell rationl. I hate roaches more than most, I’m phobic, but it’s not hard. Gutloading is easy, they eat anything. They are tropical, if they get loose they’ll likely be dead soon, if you somehow can’t catch them. They are extremely slow and calm, plus they only get 2-2 1/2 inches tops. It’s gross, but it’s the best for live feed. I don’t have all the answers, though, I would really suggest bringing him to a specialist veterinarian. I had a Cham. with a Vit. A deficiancy, and at the best office in my state I paid 50 to bring him in, 50 for treatment, and fifty for a week and a half’s board. I don’t know the pricing in your area, but my little guy was really bad off, and if didn’t cost an arm and a leg - and even if it did I would’ve done it to assure his good health and a long life for him. Reptiles don’t ever seem sick unless they are really bad off, or close to death - they have to appear perfectly healthy and aggressive in the wild or they will get eaten at the first sign of sickness. Chances are he’s really sick if you can tell he’s off. When were the bulbs last changed? That could also be a culprit. After six months it is optimal to change bulbs - the UV output drops signifigantly considering how often it is used, etc. Heat lamps and infared have similar issues. He will still need vet care, I would forcefeed until you can bring him, though, and keep him hydrated, chances are they aren’t drinking enough - or at all when they are really sick. A medicinal syringe [needleless of course] can be filled with water, and once you have his mouth open, insert the tip and keep him still. Don’t force it in too fast - he will choke or refuse to drink. It has to be slow.
