I have a dog with a huge abscess on his neck. The vet was scheduled to take it out but before it could happen it burst. It was the size of a softball and growing rapidly. So now I am treating it with a yarrow wash 2 times a day and yarrow powder afterwards. I’m wonder if I should use the poultice formula as a dry powder or a wet poultice? I’ve tried to share a picture of it so you can get the full scope of the would. If there is a way to post a pic let me know.
