Ok so the vet said it was the nail that was torn, not half the toe thank goodness. He said I could put neosporin and a cone around her neck, or give her smz antibiotic. I brought everything home with me. The end of her toe is a little red and she keeps holding up her paw. I want to cause the least amount of stress as possible, so I would rather not put a cone on her unless the toe is not healing because she is chewing on it. the vet said chinchillas sometimes chinchillas chew on their wounds. I just put some neosporin on it, but should I give her the antibiotic? It destroys all bacteria even the good bacteria which makes me hesitant, but I also don't want it to get infected. It was actually healing up quite nicely before I took her to the vet, then when I picked her up it was a little red.
