Alternatives to the "E-Collar"/Cone for a dog after surgery?

My dog was in for spay surgery 4 days ago and she was fitted for the cone of shame because she was licking her incision. She is an obsessive-compulsive chihuahua who is prone to panic attacks so as you can imagine, it’s not going very well. She isn’t trying to take off the collar, but she is having a lot of anxiety and I’m having a tough time settling her down. I’d like to take off the collar (even though I was going to keep it on for at least a week) because I feel terrible for her and I don’t want her to hurt herself. Are there any alternatives to prevent her from licking her incision?
