My dog recently splintered her toenail. At first pieces of the nail were hanging off, which eventually fell off. Then I noticed it looked sort of raw underneath - no blood though. I looked at it yesterday and it looked like something referred to on the internet as a "bloody stump". It's a raw bit of flesh that's been exposed because a portion of the nail fell off. It's not bleeding though. I wrapped gauze around the foot last night and the swelling has gone down because my dog hasn't been able to lick it as she has been doing. Is there anything I can apply to her wound such as topical cream in order to speed the healing? This has never happened before. Is there anything I should know about these sort of nail injuries? Will it heal on it's own if she doesn't keep irritating it with her licking??
