Normally the bearded dragons will do this when they are basking under the heat lamp. Bearded dragons will also have their mouth open if they have a respiratory disease.

Landrace. A landrace is a local variety of a domesticated animal or plant species which has developed largely by natural processes, by adaptation to the natural and cultural environment in which it lives.hen an animal landrace is codified as a pedigree breed without significant selective breeding to alter it, though often to lock in its defining traits, it is often referred to as a natural breed or traditional breed by breeder and fancier organisations.
However, the term is sometimes used in a very broad sense to define landrace animals, or naturally selected horses of a common phenotype located within a limited geographic region. Depending on definition, hundreds of breeds exist today, developed for many different uses.orses have been selectively bred since their domestication. Today, there are over 300 breeds of horses in the world. However, the concept of purebred bloodstock and a controlled, written breed registry only became of significant importance in modern times.
