As soon as they start drinking, their bodies puff up, they flatten their heads down, and partially close their eyes as they enjoy the drinking.
Can you see Max's happiness? He almost never drinks out of his bowl, but he did two weeks ago.
Ziggy has been the only beardie I've ever had who refuses to drink. For almost a year, I have tried to train him with NO success.
Finally, last week, he drank water off my fingers and yesterday, he drank out of the bath!
I had to use a syringe, but he drank!!
Some beardies need a LOT of patience and training. A LOT!! So keep doing the good things because eventually they will get it.
