No, bearded dragons are not poisonous.
In a sense yes. Bearded dragons, like most reptiles help keep pest type animals down. In the Bearded's case it is primarily crickets and grubs. Since crickets, grasshoppers, grubs, ets. can cause problems with many types of farms, by the reptiles keeping these creature's population down, they indirectly keep farmers employed and eating.
Probably not poisonous, but I would classify it as harmful or irritant, like cedar. It could be dangerous if ingested. I would not use it for substrate.
First off, you question has awful grammer. Im not sure if you are asking if the dragon is poisonous or the katydids, but I'm going to assume you are talking about the dragon. Yes, it is poisonous.
no bearded dragons cannot have wood chip
Yes they are - since Bearded dragons lay eggs.
Yes they do
WHY would you want to know such a thing ?... unless you're planning on feeding some to a berded dragon !
Grubs are not poisonous to dogs. Human eat grubs as a source of protein. Animals can do the same. There is no concern for the grub to even upset the stomach of a dog.
go on youtube and search up bearded dragons
its not possible for bearded dragons to mimic crickets
No, bearded dragons are not the same as frilled necked. Bearded dragons have a more wider beard as frilled neck dragons have a smaller frill around their neck.
