Q. A cyst has opened and is draining what should I do for it until I can take the dog to a vet?
A. Place an e-collar on him to prevent licking. Keep the area as clean as possible until you see the vet. Promote drainage with a warm compress. Do not give or apply any medications to your pet without the advice of your veterinarian.

A. just keep it as clean as you can so it doesn't get infected - clean it with lukewarm water and some cotton. If he is licking the area I would advice to put a buster collar on him until you can go to the vet.
