My water dragon hasnt shed in months, whats wrong?

he shed very poorly when we first got him but now some of his skin just looks dark like it was gonna shed then stopped. we've tried soaking him and spraying him everyday. also he wasnt well when we first got him and we're not convinced he was terribly well looked after before he was given to us.his motabolism was really slow so we took him to the vet who gave him a glucose and electrolites injection and he perked up alot after that. hes got a fogger for humidity and eats healthy and is active. any ideas?

Probably nothing. You could try increasing the humidity, but water dragons may only shed once a year.
Reply:When he starts growing again he will shed.Sometimes they only shed every 2-3 years.Don't worry
