sick or shedding?Please help

[belladonnamini]

My dragon is not eating near as much as he(not even 100percent sure it is a he) was, he is not as active and is not going potty as often as is normal for him. When i give him a bath we have seen some large bits floating shed in the bath but i cant tell from what part of the body.
i got my puck from a rescue and it is believed that he will be 3 this summer(we think he was 2when i got him and ill have him 1yr this summer). He recently got a clean bill of health from the vet and when i got him they told me he had just finished shedding. however i have been told they they tend to be a grayish in color when shedding and the only thing i have noticed about his color is that it is not staying as bright for as long after his bath's as it normal does.
I am not sure what is normal behavior for a dragon during shedding, if i need to do anything special for him or when i should be worried and take him to a vet.
he is my baby so i could be an over worried first time mom but i have never seen any sort of shed come off of him in his bath before
thank you in advance for any help given

Hi Bella....post a pic, it's most likely shed related. And they can change color , fade or brighten after sheds as they grow.
