Heat stress

[Gregor]

What are the signs of a heat stress in a tortoise( Sulcata, Leopard,...)?

 

[TammyJ]

The number one sign is the owner or caretaker being uncertain as to whether the tortoise may have been exposed to overheating.
If it was possible, then regardless of any apparent symptoms like weakness or unresponsiveness, immediately remove the tortoise from the potential heat source and begin the soaking treatment for dehydration.
