Frog not eating or pooping . . .

[Bynny Ribbit]

I would prioritize pooping over eating. Anytime my girl has been "backed up", she barely eats or refuses food completely, so getting a BM is your best starting point. Are you able to feel or otherwise analyze the right side of his body? You might be able to tell if he has a poop brewing, the right side of his body will feel firm or show a prominent lump.

I'm not sure of the temperature of the water you have him soaking in, but if you haven't already, try letting him sit in some warm water. Better yet, try adding a little honey to it, if you have it on hand. Hopefully one or a few sessions of a nice, warm soak will coax something out of him.

On the other hand, if his right side feels soft and there's no indication of a stool, it may be prudent to bring him into a vet. It's possible he picked up parasites, etc. at some point and was fine when he was healthy, but the stress of a new environment lowered his body's defenses and allowed the invading bodies to get out of hand. However, identifying parasites usually requires a fecal examination, so it's kind of a catch 22. This is me purely guessing on my part, but often times if a frog isn't eating due to impaction or stress, it's because something else (parasites, nematodes, etc.) is hindering his appetite.

To help you feel better about him not eating, my friend bought a baby Pacman that had a month long hunger strike, lol. Frogs can be delicate in some ways, but they are hardy in others, especially horned frogs.

I've tried warm soaks so frequently, and none of them produced anything. I hate to have to keep digging him up from the substrate as I don't want to stress him even more, but I may have to in order to examine his right side --- He was eating and pooping fine, and then everything stopped and I don't know why. Ok well wish me luck - and I will let you know what happens. Thanks.

UPDATE::: I removed him from the tank - examined him - he does not have a lump on his right side at all. So, he does not have any poop inside him. I'm now soaking him in warm water with Honey for 30-minutes. I will try to feed him again tonight and see what happens.
I will prepare to take him to the vet this week.

Yeah, I think a vet visit would be a good idea at this point, especially since he was eating before. They can give him a thorough check over and rule out other possibilities for his lack of appetite. Costs can add up pretty easily though, for me an examination is $67 without anything else included.
