Home treatment after removing a foxtail from my dog?

My dog had a foxtail stuck to the right of her butt. Thought it was a ruptured anal gland, but it was higher than the anal glands and my boyfriend saw a foxtail in there so he was able to push it out. This happened right before we were going to take her to the vet for a ruptured anal gland (so we thought), so I'm glad we figured it out. Now I was wondering what to do about the wound. It is like a cyst that ruptured when we squeezed the foxtail out. She's not in pain from appearances, and I was wondering what would be a good home treatment for the wound? For now, I've applied triple antibiotic ointment and wrapped a little handkerchief around her bottom to prevent her from licking the area. I've also shaved her bottom to prevent poo from sticking to the hair and infecting the wound. Is there anything else I need to do? Maybe like washing the wound regularly or something like that? From what I read online about foxtails, once the foxtail is out, the wound should heal up in a few days. Thanks!
