I had a big frog of that size for 2-3 years in my little 200 gallon pond. He never bothered the fish, except when he'd take down a bird too big for him to eat and I'd have to fish the bird out of the pond. Trust me, he was eating these birds. I found him with a baby in his mouth once, and one time I found a dead bird I placed it next to the pond. Next morning the bird was back in the water. Only critter that would do that was the froggie. My frog wandered off this spring, my neighbors saw him on their deck. Took pictures and wondered where he came from. Wish he'd wander back. I have another frog in my pond but I very rarely see him, he hides under my bridge so when I do maintenance I see him hop away.

Yep, southern leopard frogs, for sure. Lovely, HIGH jumping, fast moving little guys. I can't remember what their call sounds like, but the above link should help with that. Enjoy these cuties! I wish some of them would find MY pond. Marcia

It is indeed a male Bullfrog. He has likely taken up at your home due to his disability. They do go to the bottom of the pond and hibernate in the mud, but if there is no mud bottomed pond, you could take him indoors for the winter and feed him crickets. He may be able to hop pretty good, but he is a little bit a lightweight, and I suspect that he has a little trouble feeding himself. This disability may make it difficult for him to take the insects he feeds on effectively. I would try and augment his diet with crickets from the bait shop or pet store and see if he gets a little fatter. You will want to dust the crickets with reptile vitamins. With his injury, he will be unable to fend off predators, and will likely get eaten at a big pond, and if he makes it to winter, may not have enough fat stored to make it through. If it were me, I would take him in and try to make his life easier, but some are in favor of nature taking its course (which would likely be curtains for the frog). If you would like any info about how to help him, let me know; I have kept many amphibians over the years, when teaching Environmental Ed. He may also need antibiotics, to stave off infection in the stump. Unlike salamanders, frogs cannot regrow limbs. BTW: The external ear, called a tympanum, is larger than the eye, making him a male. He has no skin folds from head to groin, which cuts out Green Frog. He has a fold of skin that goes around his ear, making him a Bullfrog. See: Bullfrog on Wikipedia. Enjoy.
