i was hunting today with my 11 month old lab..she was out after a rooster, when she tried jumping between two barb wire fences. through this process she clipt herelf on the fence, but kept on going. i checked her on the field, but didnt see any major cuts. after we got home, i noticed something on her chest. as i examened it, she had a pretty deep cut, the size of a quarter. her skin is peeled back, and she is very sencitive to that area, i was treating it with some antiseptics. i was then thinkning...the barb wire fence she hit was very old, and rusty. my question is can dogs get tetnis like we humans do from rusty metal?? should i just treat her with antiseptic every day to prevent bacteria, or should i go to the vet? the cut is pretty deep, and her skin and hair is peeled back in that quarter size area. any help would be appreciated. thanks
