Well she wont stop licking it, she has actually cuased blisters all over her muzzle area from licking it. And it did open back up, but it is healing from the inside out and I have been keeping it clean and trying to keep her from licking when I clean it with peroxide

I try putting her hoodies and tanks on her so he cant mess with it but she has even eaten a hole through her sweatshirt. SHe is determined. BUT it looks like she is keeping it really clean by licking it.
