Respiratory problems are not a massive problem for bearded dragons (pogona) but, despite the lizard’s robustness to such diseases, they can still be affected. Underlying the condition are various possible pathogenic species of bacteria, viruses, and fungi and parasites. Symptoms that are likely to be observed include gaping and breathing problems as well as mucus and loss of appetite. The treatment needed could require changes in nutrition and environment. But it could also involve the use of some form of medication as appropriate for the particular pathogenic species.
There are several symptoms that you need to watch out for in cases of respiratory problems in bearded dragons. One of the most blatant ones is the gaping of the creature as it attempts to make up for the breathing difficulty it is having. In some cases forced exhalation may be observed. The lizard may also appear puffed up, especially around the throat. Other symptoms can include yellow or brown mucus around the mouth and nostrils and also a loss of appetite that may lead to further problems later on.
The first step towards treating respiratory problems in bearded dragons will be to use these symptoms and the result of examination and testing to diagnose the condition and determine which particular pathogenic species has caused the problem. With that done medication can be provided that is appropriate for that pathogen. This would mean antibiotics being used for bacterial infections or anti-fungal medication for a fungal infection, for example.
But preventative steps should also be taken to stop the condition from occurring again further down the line. This could mean analysing the diet that the bearded lizard has been provided with in the past. It may be that this has been inadequate in some way, or inappropriate for the species. In which case, the diet of the lizard will need to be modified as is appropriate for the species.
Finally, there are also the environmental conditions that the lizard is kept in to be considered too. These should be checked to make sure that the hygeine level is appropriate and improved if need be. But there are also the environmental settings of temperature, ventilation, and humidity that need to be considered as well. Bearded dragons, like all reptiles, have very specific settings that are appropriate for their species. So these will need to be checked, adjusted, and maintained at the right levels in the future.
