If you’re wondering how long can a bearded dragon go without food you’ve come to the right place. An adult bearded dragon can go up to two months without food – but it depends on why they’re going without eating. Baby bearded dragons should not go without food.
How Long Can A Bearded Dragon Go Without Food?
Adult bearded dragons will often go without eating for quite some time. Many owners worry if their bearded dragon stops eating for just a few days. There is nothing to worry about for this short period of time.
A healthy adult bearded dragon can go without eating for up to several months. They are reptiles and reptiles are built to survive the lean times when there is no food available. This is particularly so in the Australian Outback where these little lizards originate.
But, just because they can doesn’t mean they should.
Babies Are Different – They Should Not Go Without Food For Long
The metabolic requirements of a baby or juvenile bearded dragon are very different from an adult bearded dragon. An adult bearded dragon, as we mentioned can go without eating for up to 2 months with no likely detriment.
A baby bearded dragon cannot survive this long without food. We would recommend a baby or juvenile bearded dragon does not go without food for more than 3 days to a week at maximum. This is because a baby / juvenile bearded dragon is constantly growing and to do that they require constant protein and calcium input. If they go without food for more than a few days you should contact your Vet to find out if something else is wrong (hint: there will be something else wrong).

Beware The Brumation Trap
Reptiles are ectothermic so do not rely on food intake to maintain body temperature. Consequently they do not have to eat as frequently as birds and mammals. In the wild they are also capable of long periods of physiological starvation during times of drought, temperature extremes, food shortage and hibernation. Unfortunately many pet owners assume their pet is undergoing this physiological hibernation / brumation when the pet is actually starving due to illness or poor husbandry. Consequently reptiles are often presented to veterinary clinics in an advanced state of debilitation.
Reptiles are commonly kept under suboptimal conditions leading to stress and maladaptation. Common causes are inappropriate food, low temperatures and competition from tank mates. Food of appropriate size and familiar colour are often not provided.Bairbre O’Malley, MVB, CertVR, MRCVS, Bairbre O’Malley Veterinary Hospital, Nutitional Problems In Reptiles

How To Tell If A Bearded Dragon Is Starving
Most bearded dragons in captivity are actually clinically obese. They’re overfed and under-exercised.
We recommend weighing your bearded dragon on a set of kitchen scales once a week or so, particularly if they’re not eating at the moment. If their weight starts to drop by more than a few grams it might be time to see the Vet. But get used to your bearded dragon’s habits.
To see if a bearded dragon has enough fat reserves, you can look at the tops of their heads. They should have nice, fairly prominent little pads on the tops of their heads above but just behind their eyes. If you’ve ever had a baby you can think of these in a similar way to the fontanelle on a baby’s head (they’re physiologically different, but look similar).
A bearded dragon that is starving will have flat or even sunken fat pads on the top of their heads. This can also be a sign of dehydration. Bearded dragon’s also have fat pads on either side of the base of their tails. They’re not so easy to see as the fat pads on their heads but they can be felt quite easily.
You can gently grip the sides of the tail between your thumb and forefinger, just behind their rear legs. If there is not enough fat in the tail fat pads the base of the tail will feel thin, the skin may feel saggy, and you’ll be able to feel the bone of the tail easily. A healthy dragon will feel soft at this point, but not saggy.
If you’re at all unsure how long your bearded dragon should be going without food, or there’s any doubt as to why they’re not eating you should contact a vet as soon as you can. Our advice, as always, is generic in nature and only intended as a guide. For something such as this, veterinary advice is especially important.
