I'm very sorry your son's frog is not well . 4 weeks ago you asked for initial advice and we provided care article link and information to include feeding and the need for dusting: http://www.frogforum.net/pacman-frog...wner-here.html. Suggest review that thread and stop following your local pet store advice; which is already proven flawed by your frog's condition.

Here are two veterinarian locators: Arav and Herp Vet Connection. Agree with Collen/Jerrod it's not Red Leg. The bloating (specially if concentrated around rear quarters area and move as in jelly/wave like) point to another possibility. Extended exposure to day cold temps (75F average as reported) has damaged the frog's kidneys and lymph hearts. The veterinary can drain the excess fluid out and correcting temps will prevent a recurrance of bloating; but sadly, the organ damage is permanent .
