Today, my mother was outside removing monkey grass from the back of our yard using a pitchfork. Unfortunately, since it's getting colder, there was a small toad buried where she was digging. I was not there to see what happened at first, but I was told that she had been digging and something squirted into the air (not blood, maybe urine?) and she then stopped to find the underside of the toad in the dirt, at which point I was called over. Since I didn't see what happened, I'm unsure if she hit him directly or just came very close.
When I picked the little guy up, he was (and still is) very bloated. To me, it feels like he's full of air, not fluid, but that's just a guess and I can't be sure. He's moving around pretty normally, but as far as I can tell, it's been roughly 2 hours and he has not deflated at all, which I want to assume he would do if this were a defense mechanism.
Right now, we have him in a large bucket with dirt and leaves for moisture/hiding. We are in a small rural town with no veterinarian and certainly no exotic/reptile specialists. I would like any advice anybody has on whether or not we should be worried and what we can do for the little guy. Thanks in advance.
