When one of my frogs doesn’t eat for a couple of days, I naturally freak; so I understand what you're going through. However, I have developed a trick to stimulate my frog’s interest in eating.
To get my frogs to eat, I take a small container, about half a gallon in size, and line the bottom with wet paper towels. I also add a small clump of moss in there (so the frog can hide and feel secure) and place the frog inside the container. I then add three or more crickets in the container with the frog, to get him interested in eating. I leave the frog in the container in a warm, quiet location for a couple of hours or even a day if need be. This trick usually works for my frogs, as the crickets have no place to really hide and the frog can get to the crickets easier without getting a mouth full of dirt. It is especially effective if I don’t hover over the container, make a lot of noise, or check on my frog every 5 minutes. Anyways, hope this helps!!
