My iguana is weak, cold, and has yellow spots. Does he need a vet?

The brown spots could be early mouth rot or other infection. He should be examined by your veterinarian or a vet experienced in treating reptiles today. Check the temps in the tank. Low temps can affect appetite and activity in reptiles. His symptoms may also indicate nutritional deficiency. If he is cold, soak him in a warm 50/50 solution of water and unflavored PediaLyte. Offer an appropriate diet of fresh chopped greens. Supplement with a calcium and multivitamin powder as well. He should be under a heat lamp and a UVB light source. A special diet such as Oxbow Emeraid may be indicated. You can purchase this from your veterinarian after an exam.

The bumps could be infection (bacterial or fungal). An iguana that won't eat should be examined by your veterinarian or an experienced herp veterinarian. Make sure the temp in the enclosure is warm enough. Low temps can affect appetite. Symptoms may indicate MBD (metabolic bone disease), but this should be diagnosed by the vet. Soak him in a warm 50/50 solution of water and unflavored PediaLyte. This will treat or prevent mild dehydration and may help with shedding. If bloodwork shows low calcium, your vet can dispense or administer calcium supplementation.

Without an image or physical exam, it can be difficult to determine exactly what is going on. It could be a bacterial or fungal infection, skin from shedding or trauma (burn, abrasion, etc). Ideally, Iggy should be examined by your veterinarian or a vet experienced in treating reptiles. You can find one using the link below if necessary. http://arav.site-ym.com/search/custom.asp?id=3661 In the meantime, confirm proper environmental parameters. To much humidity can promote bacterial or fungal overgrowth, too little humidity can lead to difficult sheds. Make sure Iggy cannot come into contact with either the heat lamp or UVB light source. Minor infection can be treated with daily cleanings using diluted Betadine or Chlorhexidine. Clean and sanitize the cage and use plain paper towels as substrate to make cleaning easier until the issue is resolved.

Thanks for reaching out about Baby and including photos. Could you include the radiograph? The arm does appear swollen. Calcium deficiencies and metabolic bone disease, are the most common. Has the UV bulb been changed in the last 6 months? Neurological problems can also cause twitching, so if the radiographs are normal, a comprehensive reptilian profile is probably the next step, as kidney disease can also cause tremors. Good luck.

The black spots look like skin that did not shed properly. I suggest you check the cage temperature and lighting as that is the number one reason they get lethargic. Also make sure her diet is correct and you are giving her calcium supplements. ( http://www.reptilesmagazine.com/Care-Sheets/Lizards/Green-Iguana/ )

It could be a hard shed or local infection (bacterial or fungal). Soak or mist him with warm water. Cleanse the area with diluted betadine or chlorhexidine solution daily. If the spot doesn't resolve or spreads, have him examined by your veterinarian or an experienced herp vet.

The dewlap should not feel hard or firm. There are variations in color, so the yellow hue may be normal or not. You need to have Edoardo examined by your veterinarian or a vet experienced in treating reptiles to diagnose illness or injury. In the meantime, confirm proper environmental parameters and diet. See your vet sooner if you notice lethargy or decreased appetite.
