I try to put the heat lamp where he can’t reach it. But he loves smacking itThey look like spot where it got burnt from being under the heat lamp for too long! My female blue tegu had something pretty similar but worse from her trying to climb and escape my pushing the heat lamp up and burnt her self and now has a permanent scar looking thing on neck.. pretty sure yours is burns from heat lamp
When I first got my boy Pubba, he began developing these odd spots on him. When they first began developing they looked similar to what I see on your baby. I took him to the vet, & not even he could identify what it was. He suggested I try something prior to sending the scraping off to the lab. I began using povidone-iodine, diluted to the color of fresh brewed black tea, & I would soak him in a warm bath of it twice a day. The spots began healing, & a few months & sheds later they were completely gone. I assume it was some sort of bacterial infection that he had carried with him from Florida. I would suggest bathing your 'gu in iodine diluted with warm water to the aforementioned hue twice daily. If you notice improvement, keep doing so until you no longer see signs of the spots.I’ve done my research about tegus and I have not seen something that matched this photo yet. Can someone help explain what these spots mean and what I could do to help?
