She is urging fans to write to the club in an effort to get her role back.
Doncaster Rovers have refused to comment.
Ms Chandler said: "The photos were tongue-in-cheek and not seedy."
Although there had been no written contract with the club, she had been working as a mascot for over three years, she added.
"I did not tell the club I was going to do the photo as it all happened very quickly.
"I have put blood, sweat and tears into being Donny Dog and doing the charity work, and this is how they treat me."
Ms Chandler, who is the only woman mascot in the country, was approached to pose for the photos after an article about her appeared in another newspaper.
