Bearded Dragon Tail issues.

I purchased a baby bearded dragon about six inches. I have recently noticed what looks like shriveled skin on the last few centimeters of her tail. On the underside of her tail were the shriveling starts it looks almost like a kink in her tail. A dark line like you would fold a hose in half. Any idea's what this could be? Coarse of action? I will be sure to post pictures.

Without seeing a picture, I can't be sure but it sounds like either a tail nip or the tail was crushed (most likely by a tank lid). This should have been disclosed by whoever sold it to you if it happened there. The tail tip should fall off in a few days. In the meantime, you can apply a very little hydrogen peroxide and/or triple antibiotic ointment to prevent infection. The dragon should be fine but if it looks like its becoming infected (the darkness is spreading past that dark line up the tail), you'll need to take her to a vet.

It is a good portion of her tail. Something I cant see falling off. I may try the hydrogen peroxide though.
