Hi Deborah! Heather and Lija have given you good advice and apparently your frog is getting better already! The symptoms you stated do match electrolyte imbalances and that is related to frog "dragging her back legs." Once a situation becomes chronic it will take time for frog to get a full recovery. Bones, tendons, ligaments won't respond to treatments and correct water use overnight. With right conditions, good food, and the soaks things can only get better.

Have you ever tried feeding night crawlers from Walmart's sports section or a local bait & tackle shop? Just make sure they are free of chemicals like fluorescent dyes. Their nutrition level is way better than crickets. Also, try gut loading crickets with veggies or Repashy's Bug Burger. Repashy also makes a meal substitute called Meat Pie that you can add to it's diet for variety (don't add supplements the day you use it). Hope your frog's health keeps improving and good luck !
