I would follow the advice that Connie gave you - put peroxide on it and keep a close eye on it to make sure there are no signs of infection. It should heal itself nicely as long as it doesn't get infected. If anything at ALL seems "off" to you, however, take her to the vet ASAP because the earlier you catch an infection, the easier it is to get under control and get rid of. In something like this the main thing is to stop the bleeding and you have done that, so I would just keep it clean and keep an eye on it. She should be just fine, but be very vigilant for the next few days to make sure. Please let us know how she does.

Hi there...
My boxer did exactly the same thing 4 days ago. He somehow managed to rip off most of his toenail. The quick is exposed and looks horrible, red and raw. For the first 3 days, it would bleed quite easily, and he would not use his foot. Today, he has been using his foot again.
For the first 3 days, I put hydrogen peroxide on the toe, 3 times a day.
I was hoping that it would not get infected, and so far, so good. My dog did not want me to touch his toe, so all I did was pour a little peroxide on to the toe. Today, I have only applied hydrogen peroxide twice, and I will do the same tomorrow. I did not wrap his foot, as I believe it is beneficial for him to be able to lick his wound.
I have also tried to keep him in the house most of the time, so he is not running around out in the dirt and mud.
Also,
If your dog will let you, you could put some antibiotic ointment on the nail, but I would not want her to lick and ingest the ointment, so I would also wrap the foot, and apply the ointment at least twice a day.
The main thing is to keep a close eye on your dog, and watch for any possible signs of infection.
Get her to the Vet if her toe starts to look like it is getting infected.
Good Luck...Connie
