My poor Aussie wears the e-collar quite often in the summer and fall due to allergies. If we don't catch the itchiness soon enough, he just keeps licking himself raw and there's little we can do to stop it at that point. Prednisone has proven difficult because he then pees in the bed in the middle of the night , but an antihistamine seems to work if we catch the itch soon enough.

Glad your pup is feeling better!
