My puppy was chewing on, what i believe to be, a mud turtle two days ago. its a little larger than the size of my palm, so probably still a baby. I've kept it in a box in my garage with a plate of water and attempted to feed it both kale and live mealworms, but i'm not sure its eaten anything. Today i bought some anti-infection liquid for turtle water and am attempting to feed it dried shrimp with some calcium powder. I try to leave it alone in a quiet place because i don't want to stress it out more, so i cant watch it much but it does move around and burrow under the paper towels i put in there. My dilemma is that the turtle has a gaping hole in its back shell, and if you get at a low angle you can see a lot of pink and white, even yellow(possibly it's insides... which would explain why it doesn't eat maybe?). some parts of the front of the shell were chewed off but they're still intact and not that severe, as are all its limbs. It still pops its head out sometimes and can move around. I'm not sure its an injury that it can survive, and if it does die i'm wondering if it would die... more "comfortably"..... in the marsh (its own habitat) or under my care trying to save it. I wont be taking it to a vet, as its a wild animal and it seems unnecessary.
