How To Tell Age Of Bearded Dragon

Breeders Know All

If you got the bearded dragon from a pet shop, find the breeder because they know when each batch of pets was forwarded to vendors. Moreover, these breeders are more knowledgeable when it comes to determining ages. So even if you do not get to the one who delivered your pet to the shop, you may be able to get an assessment of the age of your dragon pet.

The Pet Shops

The pet shop where you got the bearded dragon might not be comfortable sharing information about the breeders, but they would know when they got the dragon themselves. The information on when they received the bearded dragon might give you an idea of how old they must be. While it is a rare practice to keep records of the ages of pets, pet shops always know when they received the pet, and hence, it becomes easier to understand how old they must have been when brought to the shop. Usually, breeders do not forward dragons to shops during the first month, and they also cannot hold on to them for more than four months.

Measure Growth

It is vital to keep a check on your bearded dragon’s growth, and even novice owners can estimate how much a dragon can grow. This means that if you see a bearded dragon, you may be able to tell if it is an infant or an adult according to the growth chart of bearded dragons that is easily accessible on the internet.

One thing that owners must keep in mind is that if you got your dragon pet from the wilderness, the growth of your pet might not be comparable to the chart. When in the wild, these bearded creatures might not grow to their full potential since their diet is unbalanced.

How to Measure Growth Of Bearded Dragon

The optimum growth of bearded dragons with a balanced diet is as follows:

  • 0-1 month: 3 to 4.5 inches
  • 2 months: 5-9 inches.
  • 4 months: 9 to 12 inches
  • 6 months: 16 inches
  • 12 months: Almost two feet, maybe an inch or two less than this

Another way to determine the age can be to notice the vital characteristics such as teeth, spikes, and even toes. If the skin is soft and the dragon looks pale, then it is young. Adult bearded dragons have harder skin, and their bodies are more formed.

Sexual maturity is also an integral feature that can help determine age. If your pet dragon is sexually mature, it means that it is more than eight months old. The more your dragon ages, the more profound the sexual behavior. Suppose your pet is almost a foot-and-a-half long, and you are not sure about its exact age, you can look under the tail, and if you see bulges, it is due to the development of sex organs. The age of your bearded dragon will be above eight months for sure!

Sexual maturity is the most accurate assessment in a way it determines that the bearded dragon is an adult.

Bearded dragons require proper nutrition at all ages, and due to the limited food items that they can consume, it is best to know what age group they belong to so you can plan their meals accordingly. As children, these creatures cannot drink milk like other infant pets.

You can plan a balanced diet for your bearded dragon to see what suits them most according to their age. At each step, the right nutrition will ensure proper growth, and without knowing the period, it is not possible to feed them foods according to their growth levels.
