Reptile Care Q&A: The Questions Every Bearded Dragon, Gecko & Snake Owner Should Ask
Reptiles are the most misunderstood group of pets in terms of their care requirements. Getting husbandry right prevents 80% of the health problems a reptile vet sees. Here's what an online vet can help you get right.
Why reptile health starts with husbandry
The majority of health problems in captive reptiles (metabolic bone disease, chronic dehydration, respiratory infections, and dysecdysis or abnormal shedding) are directly caused by incorrect husbandry. The wrong temperature gradient, inadequate UVB lighting, or an inappropriate substrate creates a chronically stressed animal with a suppressed immune system. An online reptile vet will spend more time on your setup than on symptoms, because fixing the environment fixes most of the problems.

Metabolic bone disease (MBD): the most preventable reptile illness
MBD is caused by insufficient calcium and/or inadequate UVB exposure, preventing proper calcium metabolism. In bearded dragons, it presents as soft, rubbery limbs, tremors, difficulty walking, and jaw deformity. In chameleons, it causes bone fractures from minor falls. The good news is that early MBD is reversible with the right calcium supplementation protocol and a UVB upgrade. An online vet can review your current lighting setup, dusting schedule, and diet to pinpoint where the deficiency is coming from.
Is my reptile too cold? The temperature question
Reptiles are ectotherms: they regulate their body temperature behaviourally by moving between warm and cool areas. Getting the thermal gradient right is critical: a basking spot that's too cool prevents proper digestion (causing undigested food to ferment in the gut), while a gradient that's too hot causes heat stress. Different species have very different requirements. An online vet can review your specific enclosure temperatures and help you identify whether your digital thermometer is reading accurately.
Shedding problems: causes and solutions
Complete, clean sheds indicate a healthy reptile with adequate humidity and hydration. Retained shed, particularly around the eyes (spectacles in snakes) or toe tips in leopard geckos, causes constriction that can cut off blood supply and cause necrosis. An online vet can tell you what humidity level your species requires, how to set up a humid hide, and how to safely assist a stuck shed without damaging the new skin underneath.
Respiratory infections in snakes and lizards
A snake that holds its head up, produces mucus from its mouth, or makes a wheezing sound has a respiratory infection until proven otherwise. These are almost always bacterial and almost always traceable to a thermal environment that was too cold for too long. Treatment requires antibiotics, and the underlying temperature issue must be fixed simultaneously or the infection will recur. An online vet can assess severity and advise on whether injectable antibiotics from a reptile vet are needed urgently.
Feeding refusal: when to worry and when to wait
A ball python that refuses food for four weeks in autumn is probably entering a normal seasonal brumation and is fine. A leopard gecko that hasn't eaten for three weeks while also losing weight and looking sunken-eyed has cryptosporidiosis until proven otherwise. Context is everything in reptile medicine, and an online vet who understands your species can tell the difference based on the time of year, the animal's body condition, and the enclosure conditions.
Parasites: internal and external
Newly acquired reptiles, especially wild-caught animals, should be treated as potentially carrying a heavy parasite load. Pinworm infections are near-universal in bearded dragons and usually harmless at low levels. Cryptosporidium is the opposite: a serious protozoan infection with no reliable treatment and a high mortality rate in affected snakes. An online vet can advise on whether a quarantine faecal test is appropriate for a new animal and what to do with the results.
Finding a reptile-competent vet
Reptiles are exotic patients that many general-practice vets are not experienced with. Before you have an emergency, find a vet in your area with a specific interest in herpetological medicine. An online vet consultation is a good stopgap, but it cannot replace hands-on examination, bloodwork, and radiographs for serious conditions. Use online access for husbandry guidance and triage, and build a relationship with a local reptile vet for everything else.
Key takeaways
- Most reptile illness is caused by husbandry, so getting lighting, heat, and humidity right prevents the majority of problems.
- Metabolic bone disease from low calcium or weak UVB is common and preventable; replace UVB bulbs on schedule.
- Set a proper warm-to-cool temperature gradient and verify it with an accurate thermometer.
- Retained shed around eyes and toes can cut off circulation; the fix is usually humidity.
- Open-mouth breathing or mucus points to a respiratory infection, often from being kept too cold.
- Quarantine and faecal-test new reptiles before mixing them with others.
