We decided to stop giving her the steroids to see what would happen and she has stopped having those massive nosebleeds since we took her off them. (Not sure if it's because we took her off the steroids or maybe she just has a nice blood clot formed that isn't allowing the bleeding to start.)
She did have a seizure Thur. night, and that caused her nose to bleed a little but nothing like the massive bleeds she had on Tue. and Wed.
I'll ask my vet about Vitamin K too, and I plan on picking up some Simple Solution sometime this weekend as well. Thanks for the advice!!
