Skin tenting is primarily an indicator of dehydration. When an animal is dehydrated, the skin loses its elasticity and the ability to return to its original position after being pulled or tented. This phenomenon occurs because the decreased fluid levels in the body affect the skin's turgor, making it less pliable.

In healthy, well-hydrated animals, when skin is pulled up and then released, it immediately recoils back into place due to the presence of adequate interstitial fluid. However, in a dehydrated state, the skin may remain elevated for a longer period, indicating a lack of sufficient hydration.

Dehydration can occur for various reasons, including inadequate water intake, excessive water loss due to illness, or gastrointestinal issues. Recognizing skin tenting as a sign of dehydration is crucial, as it allows for timely intervention, replenishment of fluids, and addressing the underlying causes of the dehydration.
