i dont know if this is normal. I have an 8 year old bearded dragon and i have only had him for a few months. he is great, good personality and what not. but today i was helping him get some shedded skin of his tail he didn't like it much so i stopped assuming it wasn't ready, then he stuck his tongue out to feel around the area and drool came out, like a large puddle of saliva. he was going down a pillow when he did it so, he was on an angle... but i have not ever seen him do this before. I don't know if it was just because he was walking on a downward slope or if he regurgitated or something, any help would be greatly appreciated!
