Hello! I do apologize if I am doing something wrong; surfing the
internet wielded some different results, and I wanted to join this forum in hopes I could talk
to some people with good experience!

About two weeks ago I adopted a WTF from Petco. Large, loved to eat!
But now he (she?) has no interest in food. Twice the frog threw up (what looked like the fine coconut
husk substrate I use), and has no interest in food.

I also noticed him trying to poop, but unable to get it all out.
His skin is normal, eyes are clear and has no problems soaking/crawling/climbing.

I guess my question is, what should I use/do to ease constipation? Before I take him to a vet I want
to see if I can help him first. After this I plan on changing the substrate to a very nice 'carpet' I saw at the store!
(very very soft, tried tugging and nothing came up which makes me think he wouldn't be able to eat it).

I don't want him to die, especially since he's a sweetheart and I don't want to be irresponsible, you know?

Yes, I am a first time owner and would be glad to share the tank size/humidity levels and etc!

Thank you again!
