Typically, once you get something on it and the blood clots, it doesn’t bleed anymore (even if bunny cleans it up). Don’t beat yourself up too much. It happens. All you can do is stop the bleeding and watch to make sure everything is okay.

Porky also has black nails, and I have had a few oopsies. The vet even had an oopsy once.

The bleeding has never come back once I get it stopped.

Your bunny likely wont mess with it once its all better, like said My buns both have dark nails and its impossible to see through. here are the tips my own vet gave me, hope these help ^^

copying and pasting from one of my posts. these are types from my bunnys’ vet lol

1. Where the nails begin to bend is where you should clip. This is great for rabbits with colored or black nails where you cannot see through, like my buns.
2. Clippings should be every 3 – 4 weeks
3. The quick does NOT grow with the nails. This. This surprised and confused me after so many people told me they do, and I think a lot of people make the same mistake I did due to this fear. He pretty much proved it though when he cut like 80% of her nail off, and, no blood. He actually had the vet come back in and explain this too me, because in all honesty, I did not believe it. I had been told by people who call themselves professionals that they do, but, the proof was there. Of course, the quick IS in the nails, as it is with any other animal, and it does go probably 1/8th of an inch out with the nail (at least with my bun) but it doesn’t just keep growing and growing as the nail keeps growing!
4. There were a few nails where the bend wasn’t too visible. The second length cutting tip was just a little longer than the fur.
5. Styptic powder is a life saver if the quick is nipped (more so mine than the rabbits, lol)
6. The type of clippers that everyone in there recommends is the ones that look kinda like pliers and cut like scissors.
7. Two people is definitely better than one. One to hold and comfort, the other to clip

I take mine to the vet, they are both tiny bunnies and I’d faint if I hurt either of them.
