Thread: Sores around neck?

Hey guys!

So my MC Mix Freyja has a sore under her chin, one on the side of her neck and one on back of the neck. This is usually where the collar is but is no different than any other collar I've gotten her (the safe ones) - SHe is scratching a lot, I could not find any fleas. My roommate's 2 american short-hairs aren't scratching any more than normal and have no bites/sores - They are always hanging together and all 3 will stare outside the screen door when it's open... Any ideas on what I should do to help her with scratching? Should she go to the vet?
