cut quick

hi everyone! long post sorry: i’ve just had a horrible experience trimming my girls nails :’( i’m usually quite good with her! we took our girls to the vet for first time nail trim as we were too nervous & wanted to watch someone else so it - she said one of our girls has naturally long talons...

I accidentally cut into my Guinea pig’s nail quick when attempting to trim its nails. As I was cutting it she squirmed and she squeaked loudly as it began bleeding. What can I do?

I made my baby bleeed. Ahhhhhh >. < What do I do :c I was clipping his nails. Since they are black I can't see the quick.
