Edit: I checked my frog again this morning and she is actually alive.
A few weeks ago, I was on vacation in Missouri, and found and caught a frog. I stopped by a pet store to buy it a small container and some terrarium moss, as well as a water dish and some crickets. I later did some research on the Internet and concluded that I had caught a gray tree frog.
Once I got home about three days later, I went to a pet store again and bought some terrarium soil, a fake plant, a hollow half-log, a thermometer, and a heat lamp and light bulbs for the new terrarium I was making for the frog. I thoroughly washed out the 10-gallon tank I had owned and covered the bottom of it with about an inch to an inch and a half of the soil. I then covered some of the soil with the moss I had purchased earlier, and put all of the items in the terrarium.
Once I put the frog in, it immediately went inside the hollow log, but soon thereafter came out and buried itself in the soil in about five or ten minutes.
I have had the frog for about three weeks now; as far as I can tell, it hasn't emerged itself from the soil to eat, receive sunlight, or drink any water. I have had a daytime and nighttime lamp over the top of the cage, but have just had the nighttime light on since the frog doesn't seem to be coming out at all.
Throughout the two weeks after getting the frog, there was moisture around it and I could see that it had moved around while I wasn't looking at it from time to time. I just checked it again tonight, though, and there isn't really any moisture around it like there had been a few days ago. I can't see the frog breathing, but there is some soil blocking my view of it. I misted the tank again after not having had done it for about a couple of days, and it didn't seem that the water was getting to it right away.
So, I poured a bit of water right in to the tank on the soil around where the frog was; the water did seep down to the bottom of the tank, but pretty much completely missed the frog (I'm not sure if that's because I didn't pour water in the right place, or some sort of substance secreted by the frog is repelling the water or something). I poured more water in the tank, and finally saw that the water was getting to the frog. However, the frog still hasn't moved.
I really want to dig in to the soil to where the frog is, just to make sure whether it's still alive or not, but if it's hibernating or something, I don't want to disturb it like that.
I'm very worried about my frog. Does anyone have any ideas?
EDIT: I checked the frog again this morning, and I can completely see the underside of her (there is no soil underneath her to block my view), and it looks like she is breathing. Still, could she be hibernating? Why might she be keeping herself buried?
