Small details around the face

Eyes, Mouth & Breathing

Bright eyes, a comfortable mouth, and quiet breathing are small details worth knowing well.

Breathing effort is urgent. Other changes still deserve a timely call when they persist or worsen.

Begin with the ordinary context

Shed, basking, species, and time of day matter, but they should not be used to explain away a reptile who is struggling.

Eyes change around some sheds A snake's eyes can look cloudy before a shed and clear again before the old skin comes away. Outside that familiar cycle, closed, swollen, sunken, or discharging eyes deserve attention.
Basking can include an open mouth Some lizards briefly gape while basking. Gasping, a stretched neck, bubbles, noise, or effort with each breath is different and should not wait.
The mouth is usually easy to overlook From a respectful distance, notice whether the mouth closes normally and whether there is new swelling, discharge, damaged tissue, or trouble taking food.

Changes that deserve a closer look

Watch without prying the mouth open or adding stressful handling.

Eyes stay closed or become swollen One or both eyes staying closed, swelling, discharge, cloudiness outside an expected shed, or a sudden change in appearance deserves a veterinary call.
The mouth looks sore or no longer closes normally Swelling, pus-like material, damaged tissue, bleeding, a new odor, or trouble using the mouth needs hands-on veterinary care.
Breathing looks or sounds different Nasal discharge, bubbles, repeated unusual sounds, or a change that persists needs prompt advice. Clear breathing effort is urgent.

Breathing effort cannot wait

Call a reptile veterinarian or emergency clinic now for gasping, a stretched neck, marked effort with each breath, collapse, or open-mouth breathing that is not ordinary basking.
