Non-Life Threatening Pet Medical Issues
For small cuts and grazes that don't need veterinary attention, you can apply some antiseptic a thin smear of Savlon® cream which you are able to get this from any woolworths store or chemist. Please remember though - hotspots start out small and minor, but without prompt medical attention, can become infected. If you feel you need to speak to someone, you can schedule an online consult with VetChat or Your Vet Online if you are in Australia.
Otherwise you are also able to use a teaspoon of salt in 600 ML of warm water. You should apply the salt water or Savlon cream every few hours and also dress the wound in a small amount of bandage and tape.
