Ok, I was compelled to purchase another WD today as offering to buy the WD at the pet store was getting old and they don’t seem to feed them much. Anyway Mogley is a female so we shall see what happens with the little new one. My question is, if any of the dorsal spikes are damages along the spine and down the tail, will the heal or grow back with a few sheddings or are they permanently gone. They seem to be worn down a little on the new guy and I am just wondering what to look for. Well thanks for any help.
